Given four integer arraysnums1,nums2,nums3, andnums4all of lengthn, return the number of tuples(i, j, k, l)such that: 0 <= i, j, k, l < n nums1[i] + nums2[j] + nums3[k] + nums4[l] == 0 Example 1: Input: nums1 = [1,2], nums2 = [-2,-1], ...

class Solution { public: int search(vector<int>& nums, int target) { int left = 0, right = nums.size(), middle = 0; while(left!=right){ middle = (left+right)/2; if(nums[m.
