Given a Binary Tree denoted by root node A having integer value on nodes. You need to find maximum sum level in it.
1 <= number of nodes <= 105
1 <= value on nodes <= 105
First and only argument is a root node of Binary Tree A.
Return an integer denoting the maximum sum level in the tree.
Tree: 4 / \ 2 5 / \ / \ 1 3 2 6
Tree: 1 / \ 2 3 / \ \ 4 5 8 / \ 6 7
Sum of all nodes of 0'th level is 4 Sum of all nodes of 1'th level is 7 Sum of all nodes of 2'th level is 12 Hence maximum sum is 12
Sum of all nodes of 0'th level is 1 Sum of all nodes of 1'th level is 5 Sum of all nodes of 2'th level is 17 Sum of all nodes of 3'th level is 13 Hence maximum sum is 17
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
