There are N coins kept on the table, numbered from 0 to N - 1. Initially, each coin is kept tails up. You have to perform two types of operations : 1) Flip all coins numbered between A and B inclusive. This is represented by the command "0 A B" 2) Answer how many coins numbered between A and B inclusive are heads up. This is represented by the command "1 A B". Test Case 1 Input (stdin) 4 7 1 0 3 0 1 2 1 0 1 1 0 0 0 0 3 1 0 3 1 3 3 Expected Output 0 1 0 2 1 Test Case 2 Input (stdin) 4 10 1 0 3 0 1 2 1 0 1 1 0 0 0 0 3 1 0 3 1 3 3 0 0 3 1 0 3 1 3 3 Expected Output 0 1 0 2 1 2 0
