Keyboard Letters

Given an  English word,  write an algorithm and the subsequent Python code to check if the given word can be typed using just a single row of the keyboard. (e.g. POTTER, EQUITY). Print ‘Yes’ if the letters of the word are from a single row and print ‘No’ otherwise.

Input format:

A word

Output format:

Print ‘Yes’ if all letters of the word are from same row in a keyboard

Input for the problem:

A word

Processing:

We use conditional statements to check which line the letters of the words are from.

Output :

‘Yes’ if all letters of the word are from same row in a keyboard
