# Task 1: Jumping Letters
# You are given a word having alphabetic characters only, and a list of positive integers of the same length
# Write a script to print the new word generated after jumping forward each letter in the given word by the integer in the list.
# The given list would have exactly the number as the total alphabets in the given word.
