Problem statement :
Person X and person Y were given with an queue A of size N having distinct elements, the task is to nd the next greater element for each element of the Queue in order of their appearance in the Queue. If no such element exists, output -1.
Input format
The first line contains an integer N denoting the size of the Queue. The Second line of each test case contains N space separated positive integers denoting the values/elements in the Queue A.
Output format
For each test case, print in a new line, the next greater element for each array element separated by space in order.
Constraints
