Nettet21. apr. 2024 · If we compare 2 numbers that are the same then the resulting number is 0. When we compare a number to 0 the resulting number is the compared number. 2 ^ 0 = 2. Because no bits line up. Therefore a list constructed of the following numbers will also work [2,2,2,1,1,1,1] The 1's cancel
