Understanding the Keep Multiplying Found Values by Two Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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 original is found in nums, multiply it by two (i.e., set original = 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.

Get real-time assistance for Keep Multiplying Found Values by Two problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums = [5,3,6,1,12], original = 324- 3 is found in nums. 3 is multiplied by 2 to obtain 6. - 6 is found in nums. 6 is multiplied by 2 to obtain 12. - 12 is found in nums. 12 is multiplied by 2 to obtain 24. - 24 is not found in nums. Thus, 24 is returned.
nums = [2,7,9], original = 44- 4 is not found in nums. Thus, 4 is returned.
Constraints
1 <= nums.length <= 10001 <= nums[i], original <= 1000How Interview Coder Helps with Leetcode Problems
