This is my code for the Chef and Digits Jump problem (Graph Theory Basics —DSA Learning Series) CodeChef: Practical coding for everyone …I have checked all previous post on it and tried all the test cases .All of them executed perfectly but it is still giving a wrong answer.
Brief explanation of my approach: I have created a Adjacency list using Array of ArrayList.The index of the array denotes a digit.If a digit is found to repeat in the sequence it is added to the ArrayList object at that index.
After creating the adjacency list I made a bfs traversal on the list slightly in a modified way.
(Note:–While creatinfg the adjacency list I havent taken care of the i+1 position and i-1 position.This has been taken care while performing bfs.)
While visiting each position I added the i+1 and i-1 positions to queue to be visited if not already.
And finally when i get the last position i am displaying the answer.
That was my approach…
