WebJul 6, 2024 · Check loop in array according to given constraints. Given an array arr [0..n-1] of positive and negative numbers we need to find if there is a cycle in array with given rules of movements. If a number at an i index is positive, then move arr [i]%n forward steps, i.e., next index to visit is (i + arr [i])%n. Conversely, if it’s negative, move ... WebMay 19, 2010 · If you do BFS starting from 0, it will detect as cycle is present but actually there is no cycle. With a depth first search you can mark nodes as visited as you descend and unmark them as you backtrack. See comments for a … WebApr 6, 2024 · 1 Answer Sorted by: 2 The algorithm, based on DFS, typically maintains a "visited" boolean variable for each vertex, which contains one bit of information - this vertex was already visited or not. So, none of vertices can be visited more than once. If the graph is connected, then starting the DFS from any vertex will give you an answer right away. face and gesture 2023
