Solution: Split Array Largest Sum

Explore how to solve the problem of splitting an array into k subarrays to minimize the largest sum using a modified binary search technique. Understand setting search bounds, verifying feasibility, and optimizing for the smallest largest subarray sum.

We'll cover the following...

Statement

Given an integer list nums and an integer k, split nums into k non-empty subarrays such that the largest sum among these subarrays is minimized. The task is to find the minimized largest sum by choosing the split such that the largest sum of every split of subarrays is the minimum among the sum of other splits.

Constraints:

  • 1≤1\leq nums.length ≤103\leq 10^3

  • 0≤0\leq ...
