Get real-time assistance for Make Two Arrays Equal by Reversing Subarrays problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
target = [1,2,3,4], arr = [2,4,1,3]trueYou can follow the next steps to convert arr to target: 1- Reverse subarray [2,4,1], arr becomes [1,4,2,3] 2- Reverse subarray [4,2], arr becomes [1,2,4,3] 3- Reverse subarray [4,3], arr becomes [1,2,3,4] There are multiple ways to convert arr to target, this is not the only way to do so.
target = [7], arr = [7]truearr is equal to target without any reverses.
target = [3,7,9], arr = [3,7,11]falsearr does not have value 9 and it can never be converted to target.
Constraints
target.length == arr.length1 <= target.length <= 10001 <= target[i] <= 10001 <= arr[i] <= 1000How Interview Coder Helps with Leetcode Problems
