Web Reference: For the two-sum problem, if we fix one of the numbers, say x, we have to scan the entire array to find the next number y, which is value - x where value is the input parameter. Can we change our array somehow so that this search becomes faster? Can you solve this real interview question? 3Sum Closest - Given an integer array nums of length n and an integer target, find three integers at distinct indices in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution. Can you solve this real interview question? 3Sum With Multiplicity - Given an integer array arr, and an integer target, return the number of tuples i, j, k such that i < j < k and arr [i] + arr [j] + arr [k] == target. As the answer can be very large, return it modulo 109 + 7.
