Solutions

Solutions (6-10):
Sol. Students let us understand the Logic behind this Question and lets understand how to solve it. As a first step lets first understand the logic behind the Output. If you will see the final output you will observe the following:
(i)- In each step only one word and one number is getting arranged. The words are arranged in ascending order according to the English alphabetical series from left to right.
(ii)- Numbers are arranged in increasing order from left. If number is prime number add 1 in that number. if number is even (except prime number) add 2 and if number is odd number (except prime number) subtract 1 in that number. In the final step numbers are arranged in decreasing order from left end and words are arranged in increasing order.
