Reverse a String – Complete Tutorial - GeeksforGeeks Time Complexity: O(n) for backward traversal Auxiliary Space: O(n) for storing the reversed string Using Two Pointers - O(n) Time and O(1) Space The idea is to maintain two pointers: left and right, such that left points to the beginning of the string and right points to the end of the string While left pointer is less than the right pointer, swap the characters at these two positions
Algorithm and Flowchart to Reverse a String - ATechDaily We will reverse the string by accessing the string from its last character To do so, we are starting a loop with initial value i = length – 1 In this loop, we are reversing the string, one character at a time by performing: rev = rev + character at position 'i'
