Here is source code of the Python Program to check whether a string is a palindrome or not using recursion. The program output is also shown below. defis_palindrome(s):iflen(s)<1:returnTrueelse:ifs[0]==s[-1]:returnis_palindrome(s[1:-1])else:returnFalsea=str(input("Enter string:...
Give a s, need to check every substring whether it is a palindrome or not. Brute Force T: O(n ^3) 我们利用如果s[start] == s[end], 则只需要判断s[start + 1][end - 1]是否为palindrome即可。 T: O(n ^2) 所以我们利用O(n^2) 的space来提升速度, palin[i][j] 是指s[i : j +...

Write a Python function to check whether a number is "Perfect" or not.According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also ...
Check whether the given linked list is a palindrome or not. Example: 2 3 2 5 2 true 5 4 5 6 3 4 false First list is a palindrome since the first element is same as the last and middle one is common. Second list is not a palindrome because the second element does not match the...
We can then compare the original and reversed strings to determine whether the given string is a palindrome. Let’s see a Python program to check if a string is a palindrome or not. # Enter stringword=input()ifstr(word)=="".join(reversed(word)):# cycle through the string in reverse ...
