Farthest index that can be reached from the Kth index of given array by given operations | Function to find the farthest index that can be reached.
Declare a priority queue.
Iterate the array.
If current element is greater than the next element.
Otherwise , store their difference.
Push diff into pq.
If size of pq exceeds Y.
Decrease X by the top element of pq.
Remove top of pq.
If X is exhausted.
Current index is the farthest possible.
Print N - 1 as farthest index.
Driver Code.
