0/1 Knapsack Problem: How Would You Solve It?
The 0/1 knapsack problem is solved with dynamic programming: build a table dp[i][w] representing the best value achievable using the first i items within capac…
Unbounded Knapsack Problem: How Is It Different?
The unbounded knapsack problem allows each item type to be picked an unlimited number of times, so the DP recurrence becomes dp[w] = max(dp[w], value[i] + dp[w…
What is the Minimum Path Sum Problem?
The minimum path sum problem asks for the smallest total cost of a path from the top-left to the bottom-right of a grid, moving only right or down, and it is s…
What is the Unique Paths Problem?
The unique paths problem counts how many distinct routes exist from the top-left to the bottom-right of an m x n grid when only right or down moves are allowed…
What is the Maximal Square Problem?
The maximal square problem finds the largest square of all 1s inside a binary matrix, solved in O(rows * cols) time by letting dp[i][j] represent the side leng…
How Do You Optimize Space in Dynamic Programming?
Dynamic programming space is optimized by noticing that a DP table row (or diagonal) usually only depends on the immediately preceding row, so you can replace…
