Question: Write a program that returns the case of the character? Input: e Output: lower case We shall use the concept of ASCII characters to determine the case of the character input by the user. The ASCII table can be found at this link. ASCII TABLE From this we can see the following ASCII codes:- CHARACTER ASCII CODE A 65 Z 90 a 97 z 122 Thus, to check the case we simply compare the ASCII codes. Since we are using C language, in C every character is considered as …

Question: Given an array of characters formed by a’s and b’s. The string is marked with special character ‘X’ which represents the middle of the list (for example ababa…ababXbabab…baaa). Check whether the string is palindrome or not? Input: ababXbaba Output: PALINDROME Input: ababababababbbbbXbbbbabababababa Output: PALINDROME Input: abababbbabbXabbbabbabbb Output: NOT PALINDROME This is one of the simplest algorithms. What we do is, start two indexes – one at the beginning of the string and other at the ending of the string. Each time compare whether the values at both the indexes …
