You are playing a game with integers. You start with the integer 1 and you want to reach the integer target.
In one move, you can either:
\n\nx = x + 1).x = 2 * x).You can use the increment operation any number of times, however, you can only use the double operation at most maxDoubles times.
Given the two integers target and maxDoubles, return the minimum number of moves needed to reach target starting with 1.
\n
Example 1:
\n\n\nInput: target = 5, maxDoubles = 0\nOutput: 4\nExplanation: Keep incrementing by 1 until you reach target.\n\n\n
Example 2:
\n\n\nInput: target = 19, maxDoubles = 2\nOutput: 7\nExplanation: Initially, x = 1\nIncrement 3 times so x = 4\nDouble once so x = 8\nIncrement once so x = 9\nDouble again so x = 18\nIncrement once so x = 19\n\n\n
Example 3:
\n\n\nInput: target = 10, maxDoubles = 4\nOutput: 4\nExplanation: Initially, x = 1\nIncrement once so x = 2\nDouble once so x = 4\nIncrement once so x = 5\nDouble again so x = 10\n\n\n

Constraints:
