A palindrome is a word or phrase that reads the same both backward and forward. The word ""racecar"" is an example. Create an algorithm (sequence of steps) to determine if a word or phrase is a palindrome. Try several different words or phrases to ensure your algorithm can detect the existence of a palindrome properly.

Take a string from the user input.
store the input string on any variable.
Reverse the string and store it on the other variable.
Compare both strings (character by character) using any loop.
If all the character of the string matched then print that the "Input string is a palindrome".
Otherwise, print "The inputted string is not a palindrome."

Output:

If the user inputs "ababa", then it prints that the "Input string is palindrome"
If the user inputs "ababaff", then it prints that the "Input string is not palindrome"

Explanation:

The above-defined line is a set of an algorithm to check the number is palindrome or not.
It is defined in English because the algorithm is a finite set of instructions written in any language used to solve the problem.
The above algorithm takes input from the user, compare that string with its reverse and print palindrome, if the match is found.
