Rectangle Areas Comparison

You are given a list of rectangles defined by their width and height. Your task is to compare the sum of areas of rectangles at even indices and odd indices (0-indexed). Specifically, for a rectangle with width (w) and height (h), its area is (w \times h). The rectangles at indices 0, 2, 4, ... contribute to the even-index sum, and the ones at indices 1, 3, 5, ... contribute to the odd-index sum. If the sum of areas at odd indices is greater than the sum at even indices, print odds win. If the sum at even indices is greater, print evens win. If both sums are equal, print tie.

This problem requires you to read input from standard input (stdin) and print the result to standard output (stdout).

inputFormat

The first line of input contains a single integer (N) denoting the number of rectangles. Each of the following (N) lines contains two space-separated integers (w) and (h) representing the width and height of a rectangle, respectively.

outputFormat

Output a single string which can be one of the following: odds win, evens win, or tie, based on the comparison of the accumulated areas.## sample
