How to find the last occuring index of the array in increasing stack of recursion instead of decreasing stack. (As you said in previous recursion video that we get 2 chances of getting the value from recursion, 1st is increasing stack/stack is building and 2nd is when the stack is decreasing in recursion)
Recursion(LastIndex) Crux Online
Doubt Resolved: Solution algorithm is : For finding last index of element in increasing stack of recursion you have to add one more variable in function i.e. ans, and initially you pass ans = -1. While give recursive call if you find the element at that index reinitialize ans with that index and make recursive call with new ans and si + 1. At base condition I.e. si == end, you will simply just return the ans.
