It is possible to solve this problem using loop or a recursion method but what if both are not allowed? A simple solution is to write the number 100 times in cout statement. A better solution is to use #define directive (Macro expansion)
CPP
Output: 100 times 1.
Time Complexity: O(1). As the program prints “1” only once and it has a constant time complexity of O(1).
Space Complexity: O(1). As no extra space is used in the program, the space complexity is constant and O(1).
