(a) Repetition is allowed. The letters A-Z can be used for each letter position so the maximum number of 3-letter words is 26*26*26=26^3=17576. (b) Repetition is not allowed. The number of permutations of 3 different letters out of 26 letters is 26*25*24=15600.

Is C++ a palindrome function?

How do you check if a word is a palindrome in C?
Compare the element at s[i] with the element at s[n-i-1]. If both are equal then increase the c value. Compare the remaining characters by increasing i value up to iIf the number of characters compared is equal to the number of characters matched then the given string is the palindrome.
