Palindromes A palindrome is a nonempty string over some alphabet that reads the same forward and backward. Examples of palindromes are all strings of length 1, civic, racecar, noon, and aibohphobia (fear of palindromes). You may assume that in the problems below, an input string is given as an array of characters. For example, input string noon is given as an array s[L.4], where s[1] = n, s[2] = o, s[3] = o, and s[4] = n. (a) (15 pts)...

I really need help with the code for this, in C++ please, I know there's a similar question but the answer isn't correct :[ A palindrome is a string that reads the same forwards and backwards (ignoring spaces, punctuation, and capitalization). Examples are the familiar ``If I had a hi-fi,'' the grander ``A man, a plan, a canal, Panama,'' and ``Some men interpret nine memos.'' So the goal: Design, implement, document, and test a program that reads a line of...

A palindrome is a word or phrase that reads the same both forwards and backwards. "racecar" is a palindrome. So is, "a man a plan a canal, panama" if you ignore the spacing and the comma. Discovering how to automate the detection of palindromes is a good way to test your understanding of loops and strings. The file, "hw2problem5.py", contains a function called is_palindrome(), which has a single string parameter, s. If s is a palindrome, then is_palindrome() returns the...
