  • Problem Description
    Jim’s Burgers has n hungry burger fans waiting in line. Each unique order, i,is placed by a customer at time ti, and the order takes di units of time to process.

    Given the information for all n orders, can you find and print the order in which all n customers will receive their burgers? If two or more orders are fulfilled at the exact same time t, sort them by ascending order number.

    Input Format

    The first line contains a single integer, n, denoting the number of orders.
    Each of the n subsequent lines contains two space-separated integers describing the respective values of ti and di for order i.

    1 <= n<= 10^3
    1 <= i<= n
    1 <= ti, di <=10^6
    Output Format

    Print a single line of n space-separated order numbers (recall that orders are numbered from 1 to n ) describing the sequence in which the customers receive their burgers. If two or more customers receive their burgers at the same time, print the smallest order number first.
