Problem: Triangle

Medium
30 min
Explore how to solve the triangle minimum path sum problem using dynamic programming. Understand constraints and movement rules to efficiently find the optimal path by moving to adjacent numbers in the rows below.

Statement

Given an array, triangle, return the minimum path sum from top to bottom.

You may move to an adjacent number in the row below at each step. More formally, if you are at index ii in the current row, you may move to either index ii or index i+1i + 1 in the next row.

Constraints:

  • 11 \leq triangle.length 200\leq 200

  • triangle[0].length ==1== 1

  • triangle[i].length == triangle[i - 1].length + 1

  • 104-10^4 \leq triangle[i][j] 104\leq 10^4
