- 3Sum - LeetCode
Explanation: The only possible triplet sums up to 0 Constraints: So, we essentially need to find three numbers x, y, and z such that they add up to the given value If we fix one of the numbers say x, we are left with the two-sum problem at hand!

The 3-Sum problem is a classic algorithmic problem where the objective is to find all unique triplets in an array that sum up to a specific target value, usually zero This problem is a popular interview question and is commonly used in coding challenges to test a candidate's understanding of arrays, sorting, and efficient algorithms

Another method: Subtract C 3 from all elements of the input array In the modified array, find 3 elements whose sum is 0 For example, if A= [1,2,3,4] and if you are asked to find 3SUM for C =4, then subtract 4 3 from all the elements of A, and solve it in the usual 3sum way, i e ,

3SUM is important in the theory of complexity because many problems from computational geometry, dynamic graphs, and patter matching, are reducible from 3SUM That means that we can solve 3SUM by solving a constant number of instances of those problems (with some overhead)
