I converted the List to return int[] instead however when I test it on leetcode, the output is not in the same order. Instantly share code, notes, and snippets. Originally published at designgurus.org. For example, when you calculate factorial, the base case is factorial which is 1, you mean you know the answer so you can directly return it and from there onwards recursion will unroll and calculate factorial for the given number. Their only option is to prepare smartly and learn problem-solving by focusing on the underlying problem patterns. In this pattern youll work on this and other special cases of knapsacks such as: Example challenge of subset sum: Given a set of positive numbers, determine if a subset exists whose sum is equal to a given number S. Usage: Use this technique to solve problems that follow the Fibonacci numbers sequence, i.e., every subsequent number is calculated from the last few numbers. 0/1 Knapsack is one of the most common dynamic programming patterns for coding interviews. Is there a Leetcode list of all these questions? He also divides the problems into two categories one-dimensional Dynamic Programming problems and Two-dimensional dynamic programming problems.
