If the subproblem is small enough, then solve it directly. … WebDivide the point set into two roughly equal parts A and B. Determine the closest pair of points in A. Determine the closest pair of points in B. Determine the closest pair of points …
WebOct 11, 2024 · In divide and conquer approach, exponential of x n is achieved by creating sub problems of size x n/2. They are sub problems are divided recursively until they hit to the power 1. The recursive solution to the problem is depicted in following equation. If power of x is even, then simply we can find x n by computing x (n/2) * x (n/2).
