2 Computer Programming I TA C162 . 7 Apr 2006 Palindrome problem: Algorithm Design 1. Read a string in str[0….n-1] pre condition n>=1 2. Initialize left = 0 and right = n-1 1. Repeat for left<right 3.1 str[left] != str[right] terminate with false 3.2 Increment left and decrement right 1. Terminate with true Post condition Returns false If str[left] != str[right] for any value of left>=0 and right<=n-1 Where left<right
