Coding problem1

1. Puzzle

A man fell in a 50m deep well. He climbs 4 meters up and slips 3 meters down in one day. How many days would it take for him to come out of the well?

Problem approach

On the first day, the man climbs 4 meters up and slips 3 meters down, therefore he only climbs 1 meter up totally.

On the second day, again he climbs 1 meter up, so the total distance climbed is 2 meters till the second day. Therefore, the man climbs 1 meter every day.
