- Exercise Objectives Problem Description Write a program that reads a string and mirrors it around the middle character. Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.pairRemoval(String,String,String) this is a public static function that takes three strings as arguments and returns a string. You will be given three strings, the first string is a sentence as text that contains at least one occurrence of left pattern and right pattern. The second and third arguments of the function are the left and right patterns respectively. Left pattern and right pattern are single characters strings that you are attempting to remove from the string. Your goal is to remove only the patterns when left pattern has an equal number of corresponding right patterns.// write a function that takes the input string and reverses it// example// argument: Hello// return: olleHfunction reverseThisString(string){ } // write a function that takes the input string and switches all uppercase characters to lowercase and lowercase charcaters to uppercase// example:// argument: Hello World// return: hELLO wORLDfunction swapCase(string) { } //convert array of numbers from farenheit to celcius// example:// argument: [23, 32, 41, 50, 59]// return: [-5, 0, 5, 10, 15]// hint: use Array.mapfunction toCelcius(array){ } //write a function that takes an input array and returns an array of booleans (>=75) or fail (<75)// example:// argument: [20, 30, 50, 80, 90, 100]// return: [false, false, false, true, true, true]// hint: use Array.mapfunction passOrFail(array){ } //write code that loops through the two variables returns an array ['2 is zwei', '3 is drei', '4 is vier', '5 is fünf', '6 is sechs']// example:// return: ['2 is zwei', '3 is drei', '4 is vier', '5 is…
- def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.In C programming language Question (Strings) Write a function find_Substring() that finds a substring into a string. Pass array s1 and s2 to this function and prints if the substring is present or not. Expected Output 1: Enter string This is a javascript Enter substring script The substring is present Expected Output 2: Enter string This is a javascript Enter substring Jscript The substring is not presentExercise2: Thestrcmp(string1,string2)function comparesstring1to string2. It is a value returning function that returns a negative integer if string1 < string2, 0 if string1 == string2, and a positive integer if string1 > string2. Write a program that reads two names (last name first followed by a comma followed by the first name) and then prints them in alphabetical order. The two names should be stored in separate character arrays holding a maximum of 25 characters each. Use the strcmp() func- tion to make the comparison of the two names. Remember that 'a' < 'b', 'b' < 'c', etc. Be sure to include the proper header file to use strcmp(). Sample Run 1: Please input the first name Brown, George Please input the second name Adams, Sally The names are as follows: Adams, SallyBrown, George Sample Run 2: Please input the first name Brown, George Please input the second name Brown, George The names are as follows: Brown, GeorgeBrown, GeorgeThe names are the same
- Static Length, Limited Dynamic Length, and Dynamic Length String implementations have what advantages and disadvantages?7. The following function converts a postfix expression to an infix expression assuming the expression can only contain unsigned integer numbers and +' and -' operators. 1. public static String convert (String postfix) { 2. String operand1, operand2, infix; 3. Stack s = new AStack; 4. int i = 0; 5. while (i < postfix.length) { char nextc = postfix.charAt (i); if ((nextc 6. 7. '+')|| (nextc == '-') { == operand2 = s.pop (); operandl = s.pop () ; infix = '(' + operandl + nextc + operand2 + ')'; s.push (infix); i++; 8. 9. 10. 11. } 12. else if (Character.isDigit (nextc)){ int start = i; while (Character.isDigit (postfix.charAt (i)) i++; infix = postfix.substring (start, i); s.push (infix); 13. 14. 15. 16. 17. } else i++; 18. 19. } 20 return s.pop () ; 21. } (a) Rewrite only the lines of code that need to be changed so that the above function converts a postfix expression to a prefix expression. (b) Describe in words what changes are needed on the above given convert () function so that it…String Manipulation In this question, you will be implementing the following functions int findChar(char * str, char c); Searches for the character c in the string str and returns the index of the character in the string. If the character does not exist, returns -1 int replaceChar(char * str, char c1, char c2); Searches for the character c1 in the string str and if found, replace it with c2.The function returns the number of replacements it has performed. If the character does not exist, returns 0. int removeChar(char * str1, char * str2, char c); Creates a copy of str1 into str2 except for the character c that should be replaced with ‘*’ For example, if str1=”Hello World” and c=’l’ then the function should make str2=”He**o Wor*d” int isPalindrome(char * str) Checks to see if a string is Palindrome(reversible). If it is, returns 1, otherwise returns 0. A palindrome string reads similarly from left to right and from right to left like madam, level, radar, etc. int reverseString(char…
- Exercise 1: Word Separator Write a program that accepts as input a sentence in which all of the words are run together, but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string StopAndSmellTheRoses. would be converted to “Stop and smell the roses.” Exercise 2: replaceSubstring Function Write a function named replaceSubstring. The function should accept three string object arguments. Let’s call them string1, string2, and string3. It should search string1 for all occurrences of string2. When it finds an occurrence of string2, it should replace it with string3. For example, suppose the three arguments have the following values: string1: “the dog jumped over the fence” string2: “the” string3: “that” With these three arguments, the function would return a string object with the value “that dog jumped over that fence.” Demonstrate the…remove_substring_from_string(s, substr): This function takes two strings s and substr as input. It creates a new string from the original string s by removing all instances, if any, of the string substr, and then returns the new string. >>> remove_substring_from_string("Python is best language except for C++. except for C++") 'Python is best language.
