Solving Codeforces 1692F: 3SUM Problem Analysis
Approach 1: Brute Force Method
A straightforward solution involves checking all possible combinations of three indices using nested loops. This approach iterates through every possible triplet (i, j, k) in the array.
The time compleixty is O(T × N³), which is impractical given the constraint 3 ≤ n ≤ 2 × 10⁵. This method would exceed time limits ...
