This is a Python Program to check whether a string is a palindrome or not using recursion. Problem Description The program takes a string and checks whether a string is a palindrome or not using recursion. Problem Solution 1. Take a string from the user. 2. Pass the string as an ...
71. Write a Python program to print a list of primes in a given range. In this program where we need to check if the number is a prime number or not, we are making use of a very simple approach. Firstly we need to understand what is a Prime Number. A whole number greater than ...
