Jun 12, 2024 · Longest Increasing Subsequence, Shortest Path. Two Approaches: Memoization (Top Down) Tabulation (Bottom Up) Examples: Floyd Warshall Algorithm, Bellman–Ford Algorithm for Shortest Paths. BackTracking. Backtracking is an algorithmic paradigm that tries different solutions until finds a solution that “works”.
Jun 26, 2024 · Given two strings, S1 and S2, the task is to find the length of the Longest Common Subsequence, i.e. longest subsequence present in both of the strings. A longest common subsequence (LCS) is defined as the longest subsequence which is common in all given input sequences.

Jun 16, 2024 · I'm doing https://leetcode.com/problems/longest-increasing-subsequence/. I know in theory that each index needs to be assigned a length but i'm having trouble coding it up using my iterative approach. /**. * @param {number[]} nums. * @return {number}
3 days ago · The task is to find the sum of the contiguous subarray within a arr [] with the largest sum. Example: Input: arr = {-2,-3,4,-1,-2,1,5,-3} Output: 7. Explanation: The subarray {4,-1, -2, 1, 5} has the largest sum 7. Input: arr = {2} Output: 2.

Jun 24, 2024 · Add greater<p>() for longest non-increasing subsequence auto it = lower_bound(all(res), p{a[i], -1}); if (it == res.end()) res.emplace_back(), it = res.end() - 1; *it = {a[i], i}; prev[i] = it == res.begin() ? 0 : (it - 1)->second; } int L = sz(res), cur = res.back().second; vector<I> ans(L); while (L--) ans[L] = cur, cur = prev[cur]; return ans; }
Jun 14, 2024 · The Longest Increasing Subsequence (LIS) problem can be formally defined as follows: Given a sequence of integers, find the longest subsequence such that all elements of the subsequence are sorted in increasing order. Example. Consider the sequence: [10, 22, 9, 33, 21, 50, 41, 60, 80]
Jun 26, 2024 · CodeForces - 568E. Note that the memory limit in this problem is less than usual. Let's consider an array consisting of positive integers, some positions of which contain gaps. We have a collection of numbers that can be used to fill the gaps. Each number from the given collection can be used at most once.
