Oct 21, 2020 · Replace all of the O’s in the matrix with their shortest distance from a guard, without being able to go through any walls. Also, replace the guards with 0 and walls with -1 in output matrix. Expected Time complexity is O(MN) for a M x N matrix. Sep 23, 2020 · The distance between two nodes can be obtained in terms of lowest common ancestor.Following is the formula. Dist(n1, n2) = Dist(root, n1) + Dist(root, n2) - 2*Dist(root, lca) 'n1' and 'n2' are the two given keys 'root' is root of given Binary Tree. 'lca' is lowest common ancestor of n1 and n2 Dist(n1, n2) is the distance between n1 and n2.

Apr 19, 2015 · Proof that BFS finds shortest distance Posted by czxttkl April 19, 2015 Leave a comment on Proof that BFS finds shortest distance Intuitively, Breadth-First Search (BFS) can find shortest distances from a source to any other reachable vertex. Given two integersLandR, find the count of numbers in the range[L, R](inclusive) having a prime number of set bits in their binary representation. (Recall that the number of set bits an integer has is the number of1s present when written in binary. This is a follow up of Shortest Word Distance. The only difference is now word1 could be the same as word2. Given a list of words and two words word1 and word2, return the shortest distance between these two words in the list. word1 and word2 may be…
