public class Solution extends Object
1342 - Number of Steps to Reduce a Number to Zero\. Easy Given an integer `num`, return _the number of steps to reduce it to zero_. In one step, if the current number is even, you have to divide it by `2`, otherwise, you have to subtract `1` from it. **Example 1:** **Input:** num = 14 **Output:** 6 **Explanation:** Step 1) 14 is even; divide by 2 and obtain 7. Step 2) 7 is odd; subtract 1 and obtain 6. Step 3) 6 is even; divide by 2 and obtain 3. Step 4) 3 is odd; subtract 1 and obtain 2. Step 5) 2 is even; divide by 2 and obtain 1. Step 6) 1 is odd; subtract 1 and obtain 0. **Example 2:** **Input:** num = 8 **Output:** 4 **Explanation:** Step 1) 8 is even; divide by 2 and obtain 4. Step 2) 4 is even; divide by 2 and obtain 2. Step 3) 2 is even; divide by 2 and obtain 1. Step 4) 1 is odd; subtract 1 and obtain 0. **Example 3:** **Input:** num = 123 **Output:** 12 **Constraints:** * 0 <= num <= 106
