You are given a rectangular table3 × n. Each cell contains an integer. You can move from one cell to another if they share a side. Find such path from the upper left cell to the bottom right cell of the
dp[i][2] = max(dp[i][2] , dp[i - 1][3] + sum(i , 0 , 2)); dp[i][3] = max(dp[i][3] , max(dp[i - 1][0] , dp[i - 1][2]) + sum(i , 0 , 2)); } cout << dp[n][2] << endl; return0; }
We have to find the maximum path from (1, 1) to any cell in the last row. Allowed moves are right, left, and bottom. I've used DP to solve this problem, where DP[i][j]DP[i][j] equals the maximum path sum from (1, 1) to (i, j). Then I got 2 cases: the first one...
Find such path from the upper left cell to the bottom right cell of the table that doesn't visit any of the cells twice, and the sum of numbers written in the cells of this path is maximum possible. Input The first line contains an integer n (1 ≤ n ≤ 105) — the numb...

I came across this problem in which you have been given a directed graphG=(,E)G=(V,E)with||105and one additional edge can be added toEE. What can be the maximum size of a strongly connected component in the resulting graph?

The diameter (aka "longest shortest path") of a connected undirected graph is the maximum number of edges in theshortest path between any pair of its vertices. The degree of a vertex is the number of edges incident to it. Given a sequence ofnn integersa1,a2,…,ana1,a2,…,an construct...
