Keep Multiplying Found Values by Two
You are given an array of integers nums. You are also given an integer original, which is the first number that needs to be searched for in nums.
You then do the following steps:
- If
originalis found innums, multiply it by two, i.e. setoriginal = 2 * original. - Otherwise, stop the process.
- Repeat this process with the new number as long as you keep finding the number.
Return the final value of original.
Example 1
Input
nums = [5,3,6,1,12], original = 3Output
243, 6, and 12 are found in
nums and repeatedly doubled, but 24 is not found, so 24 is returned.Example 2
Input
nums = [2,7,9], original = 4Output
44 is not found in
nums, so 4 is returned.Constraints
- 1 <= nums.length <= 1000
- 1 <= nums[i], original <= 1000
