Problem 2 [1 pt]. Given a binary tree, sum the values in nodes at the same 'level', where a level of a node is the distance from the node to the root. For example, the root is at level 0 , and its children are at level 1 . In the example below, the sum at level 0 is 3 ; the sum at level 1 is 6 ; the sum at level 2 is 16 ; and the sum at level 3 is 11 . Attached is a program 'levelsum.c' which has a function int levelsum(struct TreeNode * root, int level); which returns the sum at level 'level' for the tree 'root'. The main() program will display the sum. Note that the tree that is built in the program is shown in the figure above. The current version of 'levelsum( )' doesn't work, so make it work by only modifying 'levelsum( )
