TitleGiven a binary tree and a sum, determine if the tree has a root-to-leaf path such this adding up all the values along the Path equals the given sum.For Example:Given The below binary tree sum = 22 and , 5 /

Given a binary tree containing digits from only 0-9 , each root-to-leaf path could represent a number.An example is the Root-to-leaf path 1->2->3 which represents the number 123 .Find The total sum of all root-to-leaf numbers.For example, 1 /

Given an array nums and a target value K, find the maximum length of a subarray that sums to K. If there isn ' t one, return 0 instead. 1= [1,-1, 5,-2, 3], k = 3,return 4. (Because the Subarray [1,-1, 5,-2] sums to 32= [-2,-1, 2, 1], k = 1,return 2.
