I’m working on a problem (Its from ICPC Finals 2023 actually called Bridging the gap ) involving a group of walkers who need to cross a bridge at night. Here are the details:

Given this problem formulation and the official solution in the code block:

The problem is from leetcode (link – https://leetcode.com/problems/the-number-of-ways-to-make-the-sum/description/ )

In the longest strictly increasing subarray problem, we have an array A, and we need to find the longest subarray such that in that subarray S, S[k]>S[k-1].
Since we can divide the array A into subarrays, how is dynamic programming solution /a/14492948/12862712 useful for this?

The rod cutting problem is described in section 15.1 of the book “Introduction to algorithms” by Carmen et.al. We are given an array, p where p[j] represents the money we’ll get for a rod of length j. Given a rod of length n, what is the most money that can be made by cutting it optimally and selling the pieces?

Problem An array ???? of ???? non-negative integers is said to be good if all the elements of ???? can be made equal to 0 using the following operation some (possibly, zero) times: Select two distinct indices ???? and ???? (1≤????<????≤????) and subtract 1 from all ???????? such that ????≤????≤???? . You are given two […]
