Complexity is a measure of how long an algorithm is expected to take and/or how much space is required to complete the task. It is not specific to C++ -- the language is immaterial -- it only applies to algorithms. Complexity is often expressed in big O notation, where O(1) is constant time (the best that can be expected of any algorithm).
time complexity is 2^57..and space complexity is 2^(n+1).

Another Answer: 12*0+1 = 1
it equals 62
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 11 - 9,999,999 = - 9,999,978
The algorithm will have both a constant time complexity and a constant space complexity: O(1)
