## Python | program to check each string in the list of strings whether it is palindrome or not and showing that result in the list of tuple forms.

A string is said to be palindrome if the reverse of the string is the same as the string. For example, “naman” is a palindrome, but “ankit” is not a palindrome. Iterative Method: Run a loop from start to half of the length of the string. Check the first character to the last character of […]

## Python – Sum of product of each element with each element after it in the List.

Given a list l of n integers. The task is to find the sum of the product of each element with each element after it in the list. In other words, we have to find the sum of the product of each l[i] with each l[j] such that j > i. Let’s see an example […]
