- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.10. Draw a DFA of strings where the 2nd last symbol is a. Σ= {a,b} [You may draw the NFA for this problem if you find it difficult to solve using DFA] Or, Draw a DFA of strings where the 3rd last symbol is 1. = {0,1} [You may draw the NFA for this problem if you find it difficult to solve using DFA]A set of expressions is unifiable if and only if there exists only one (unifying) substitution that make the expressions identical.i-Trueii-False
- A palindrome is a string that reads the same forwards or backwards; for example dad, mom, deed are palindromes (i.e., reversing a palindrome produces the same string). Use C++ Programing language Write a recursive, boolean-valued function, isPalindrome that takes a string as a parameter and returns whether the string is a palindrome. A string, s, is a palindrome if: s is the empty string or s consists of a single letter (which reads the same back or forward), or the first and last characters of s are the same, and the rest of the string (i.e., the second through next-to-last characters) form a palindrome. Write a test program that reads a string from the standard input device and outputs whether the input string is a palindrome or not.a) Give an example of a string in the language of (0*10*)+. b) Give an example of a string that is not in the language of (0*10*)*.C Programming Problem: Mike loves different strings but he has no interest in programming. So, his mentor thought to give him a problem of programming including problem including strings. The problem goes like this that a box has string S and it also contains another string Y. Now he has to string Y in S and the condition is that he can arrange the characters of S in such a way that Y is there in the string. Develop a C code to find out the smallest substring of S that contains Y, print the resultant string as the output. Sample Input: 1 knarameanany kar Output: aaaekarmnnny
- Help with a lisp function (please post photos) A lisp function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". For this purpose, create a global variable before the function containing the days of the week as a list. Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt function. We want the name of the day to appear capitalized. For this, extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day.…Stack using C++ programmijng language please Write a program to input an arithmetic expression, then 1.

- Code in C++ Language STRING FLIP ALPHABET One of the simplest cryptography technique is to invert the characters such that the first character of the alphabet will be replaced to the last character, the second character be replaced to the second to the last, and so on. So all A's are turned into Z's, B to Y, C to X, and so on until X to C, Y to B, and Z to A. In a similar fashion, numeric characters will also be inverted such that 0 will become 9, 1 to 8, 2 to 7 and so on until 7 to 2, 8 to 1, and 9 to 0. Given a string composed of uppercase and lowercase letters, numbers, and spaces, your task is to invert them. You also must keep the case of the letters as is. Input: A string composed of uppercase and lowercase letters, numbers, and spaces. The quick brown 1 Fox jumps over the 6 lazy Dogs Output: The inverted string Gsv jfrxp yildm 8 Ulc qfnkh levi gsv 3 ozab Wlth5. Let R1 and R2 be regular expressions. Explain how to produce a regular expression R which describes the intersection of L(R1) and L(R2).Q2/ (a) A student is given 3 tests, each marked out of 100. The student passes if his average mark is greater than or equal to 50 and fails if his average mark is less than 50. Prompt for the 3 marks and print pass if the student passes and fail otherwise. Write a program in C language to solve this.
