Hi, so all the question asks is u are given 2 node values and u have to find if they are cousins of each other or not… so two nodes are cousins if firstly they are present at the same level in tree and secondly they are not children of same nodes…
coming to time and space complexity we are doing a normal tree traversal so time complexity comes out to be O(N) and constant space is being used so space complexity is O(1)…
