30.2 LAB: Reverse a string Write a recursive function called reverse_string() that takes in a string as parameter and returns the string in reversed order. The main function is provided to read a string from the user and call the reverse_string() function. Ex: If the input of the program is: Hello the reverse_string() function returns and the program outputs: Reverse of "Hello" is "olleH". Ex: If the input of the program is: Hello, world! the reverse_string() function returns and the program outputs: Reverse of "Hello, world!" is "!dlrow, olleH". Hint: Move the first character to the end of the returning string and pass the remaining sub-string to the next reverse_string() function call.

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.
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.
Computer Science ****Please Write a program CODE in C 2. Write a function which takes a string of any length and returns the number of times the letter a appears in the string. Write the main program, which prompts the user to enter a sentence (up to 100 characters) and uses the function to find the number of times a occurs in the sentence. Print the result.

3. String (a) Write a Python function that accepts a string s and an integer n with a single digit (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) as its arguments, and returns a new string that replaces every digit n found in s by a new digit that equals to (n + 1) %10. The function returns an empty string if n is not a single digit integer or is negative.

String Pair // Problem Description // One person hands over the list of digits to Mr. String, But Mr. String understands only strings. Within strings also he understands only vowels. Mr. String needs your help to find the total number of pairs which add up to a certain digit D. // The rules to calculate digit D are as follow // Take all digits and convert them into their textual representation // Next, sum up the number of vowels i.e. {a, e, i, o, u} from all textual representation // This sum is digit D // Now, once digit D is known find out all unordered pairs of numbers in input whose sum is equal to D. Refer example section for better understanding. // Constraints // 1 <= N <= 100 // 1 <= value of each element in second line of input <= 100 // Number 100, if and when it appears in input should be converted to textual representation as hundred and not as one hundred. Hence number…
The function “reverse” reverses a given string and returns a pointer to the resulting string. Complete the missing parts. char* reverse( char* str ) { int n, h, j, k; char _________________; n = strlen( _____________); h = (n / 2); for ( j=0, k=(n - 1); (j < h); j++, _____________________ ) { tmp = ___________; str[k] = str[j]; str[j] = _______________________________; } return ________________________;} int main( int argc, char** argv ) { char s[512]; strcpy( s, argv[1] ); printf( "Reverse: %s\n", reverse( s ) ); return 0;}
PYTHON Problem Statement Implement a function which takes two arguments: the first is a string and the second is a single character (as a string). This function should move every instance of the given character in the string to the end of the string, and then return (do NOT print) the final string. NOTE: Only write code within the function. You do not need to utilize the "input()" function. The autograder passes inputs directly to the function as arguments, and the checked output is the returned value from the function. Sample Input "hello how are you?", "o" Sample Output "hell hw are yu?ooo" Starter Code def move_character(word, character):

Q Search kola shreya@columbus X275: Recursion Programming Exercise: Check Palindrome X275: Recursion Programming Exercise: Check Palindrome Write a recursive function named checkPalindrome that takes a string as input, and returns true if the string is a palindrome and false if it is not a palindrome. A string is a palindrome if it reads the same forwards or backwards. Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position a and continuing to (but not including) the character at position b.
