Bartleby answered my homework and
Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.
Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates.
Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following.
aaa has duplicatesabc has no duplicates
Print a line like one of the above for each of the strings in test_dups.
True needs to be defined. I tried to code it but didn't accept and got an error message.
The following words have three consecutive letters that are also consecutive letters in the alphabet: THIRSTY, NOPE, AFGHANISTAN, STUDENT.
Write a program that accepts a word as input and determines whether or not it has three consecutive letters that are also consecutive letters in the alphabet.
I got help from expert for this problem. But I would like to see other solution without using len and ord functions if it possiable.
please code in python
Write a function that receives a string as an input and returns the most frequent letter from the given string. Your solution should be case insensitive, so a capital letter (like A) and its non-capital version (a) should be counted as the same letter. In the given string there can be spaces as well, but your solution shouldn’t count spaces. If there are multiple letters with the same occurrence, you can decide which one to return.

- Write a function that takes a String and checks whether or not it ends with one of "T", *?.", or *" Return true if it does, otherwise false. Try writing your solution using regular String methods and again as a RegExp Using your solution, do a check on the following sentences: a sentence ending with!arrow_forwardWrite the code in python to define a function has_repeat(mystr), which takes a string parameter and returns a boolean result. - If mystr has a character that is repeated (count is more than 1 for that character), return True - Otherwise, return False Hint: You can solve this problem by iterating over the characters in mystr and comparing each character's count with 1. For example: Test Result print(has_repeat("Happy")) True print(has_repeat("sad")) False print(has_repeat("salmons")) True print(has_repeat("Trouts")) Falsearrow_forwarduestion 42: Return whether a string consists of a single letter In the function below, return True if the input string parameter consists of a single uppercase letter; otherwise, return False. Most solutions would do this in two logical steps: first testing if the string consists of a single character and, second, testing whether that character is one of the uppercase letters (which can be done by seeing if it is alphabetically between A and Z, inclusive).arrow_forward
- Two words are anagrams if they are formed by rearranging the letters of another, such as cinema, formed from iceman, and vice versa. Implement an anagram checker function using string functions in C. Your program should be able to: 1. Scan for the two words to be checked 2. Pass those two words to a function called areAnagrams which returns an int to be interpreted in the main() whether the given words are anagrams or not. 3. The program should loop indefinitely until the words "EXIT NOW" is used as input. Sample Run: Enter two strings: cinema iceman cinema and iceman are anagrams! Enter two strings: almost atoms almost and atoms are NOT anagrams Enter two strings: vice versa vice and versa are NOT anagrams! Enter two strings: frail flare frail and flare are NOT anagrams! Enter two strings: algorithm logarithm algorithm and logarithm are anagrams! Enter two strings: EXIT NOWarrow_forward: Given a string, write a function to check if it is a permutation ofa palindrome. A palindrome is a word or phrase that is the same forwards and backwards. Apermutation is a rearrangement of letters. The palindrome does not need to be limited to justdictionary words.EXAMPLEInput: Tact CoaOutput: True (permutations: "taco cat'; "atco eta·; etc.)arrow_forwardIn Kotlin A. Write a function lengthGreaterThan() with an expression body that takes a String s and an Int n and returns true if the String is at least n characters long. Then revise the function so that it can accept null values. If it receives null as the parameter, it should return false. B. Write a recursive function with an expression body that takes a list of nullable Strings and and Int an returns a list of just the Strings from the original list for which the function you wrote in the first part returns true C. Get the same result as in part B by using filter()arrow_forward
- Write a function that determines if two strings are anagrams. The functionshould not be case sensitive and should disregard any punctuation or spaces.Two strings are anagrams if the letters can be rearranged to form each other.For example, “Eleven plus two” is an anagram of “Twelve plus one”. Each stringcontains one “v”, three “e’s”, two “l’s”, etc. Test your function with severalstrings that are anagrams and non-anagrams. You may use either the string classor a C-style string. use c++arrow_forward2. Write a Python program that uses a function to find and return the factorial of a positive integer n. The function the receives a value and returns its factorial. If the passed parameter is negative, the function return the string "ERROR". Factorial of zero is one. Test your function. If n is a positive integer, n factorial denoted by nl is a product of all positive integers less than or equal to n. It is defined by =n(n-1)(n-2)..(2)(1) As a special case: 0! 1 3. In a new program, use the function you wrote in question 2 to print the factorials of values from 1 to 10. Use for loop.arrow_forwardWe can assign a value to each character in a word based on their position in the alphabet (a = 1, b = 2, ..., z = 26). A balanced word is one where the sum of the values on the left side of the word equals the sum of the values on the right side. For odd-length words, the middle character (balance point) is ignored. Write a function that returns true if the word is balanced and false if it is not. Examples balance("zips") → true // "zips" = "zi|ps" "zips" = 26+9 | 16+19 = 35 35 = true balanced ("brake") → false // "brake" = "br|ke" = 2+18 11+5 = 2016 = false liarrow_forward
- Write a function vowelIndex that accepts a word (a str ) as an argument and returns the indexof the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upperand lower case vowels count, and 'y' is not considered to be a vowel. #note that the language is Pythonarrow_forwardWrite the function strend (s ,t ), which returns 1 if the string t occurs at the end of the string s, and zero otherwise.arrow_forwardWrite the function that takes three dimensions of a brick: height(a), width(b) and depth(c) and returns true if this brick can fit into a hole with the width (w) and height(h). Examples doesBrickFit(1, 1, 1, 1, 1) → true doesBrickFit(1, 2, 1, 1, 1) → true doesBrickFit(1, 2, 2, 1, 1) false Notes • You can turn the brick with any side towards the hole. • We assume that the brick fits if its sizes equal the ones of the hole (i.e. brick size should be less than or equal to the size of the hole, not strictly less). • You can't put a brick in at a non-orthogonal angle.arrow_forward
