Senior Software Engineer

Write a program to do basic string compression. For a character which is consecutively repeated more than once, replace consecutive duplicate occurrences with the count of repetitions.

Example:

If a string has 'x' repeated 5 times, replace this "xxxxx" with "x5".
The string is compressed only when the repeated character count is more than 1.

Note:

Consecutive count of every character in the input string is less than or equal to 9. You are not required to print anything. It has already been taken care of. Just implement the given function and return the compressed string.

You have been given a Binary Tree of 'n' nodes, where the nodes have integer values. Your task is to return the In-Order traversal of the given binary tree.

For example :

For the given binary tree:

The Inorder traversal will be [5, 3, 2, 1, 7, 4, 6].
