Tintin is growing plants along a line. He notes their heights in an array. He wants to find out if there is a group of 4 plants such that their heights are in increasing order and differ only by 1 each?

Given an array with the heights, you have to print True or False.

Example: for [1,2,3,4,0], you should print True because there is a group 1,2,3,4 that matches our criteria. Example: for [1,2,3,0,4,5,0,6,7,0,8,9], you should print False because the required group is not present.

Write programming logic for the above.
