Problem: Minimum Cost to Connect Sticks

Medium
30 min
Explore strategies to solve the minimum cost to connect sticks problem using heaps. Learn how to combine sticks optimally by minimizing cost and applying heap data structures for efficient problem-solving.

Statement

You are given a set of sticks with positive integer lengths represented as an array, sticks, where sticks[i] denotes the length of the ithi^{th} stick.

You can connect any two sticks into one stick at a cost equal to the sum of their lengths. Once two sticks are combined, they form a new stick whose length is the sum of the two original sticks. This process continues until there is only one stick remaining.

Your task is to determine the minimum cost required to connect all the sticks into a single stick.

Constraints:

  • 11 \leq sticks.length 103\leq 10^3

  • 11 \leq sticks[i] 103\leq 10^3
