WebYou can explicitly transform a recursive program into an iterative one by creating a single struct containing all the variables in one function call, and a stack that contains these structs. In a loop, push or pop from this stack when you would call or return, respectively. This is what the language is ultimately doing in memory anyways.

The idea is to try all possible combinations for the first element and recursively explore the remaining elements to check if they will lead to the solution or not. If the current configuration doesn’t result in a solution, backtrack. WebJan 26, 2024 · Here is the recursive solution in python: def isPalindrom (strng): if len (strng) == 0: return True if strng [0] != strng [len (strng)-1]: return False return isPalindrome (strng [1:-1]) This function returns True if the string is a palindrome and false otherwise.
