You are given two positive integer arrays nums and target, of the same length.
In a single operation, you can select any subarray of nums and increment each element within that subarray by 1 or decrement each element within that subarray by 1.
Return the minimum number of operations required to make nums equal to the array target.
Examples
Example 1
Input: nums = [3,5,1,2], target = [4,6,2,4]
Output: 2
Explanation:
We will perform the following operations to make nums equal to target : - Increment nums[0..3] by 1, nums = [4,6,2,3] . - Increment nums[3..3] by 1, nums = [4,6,2,4] .
Example 2
Input: nums = [1,3,2], target = [2,1,4]
Output: 5
Explanation:
We will perform the following operations to make nums equal to target : - Increment nums[0..0] by 1, nums = [2,3,2] . - Decrement nums[1..1] by 1, nums = [2,2,2] . - Decrement nums[1..1] by 1, nums = [2,1,2] . - Increment nums[2..2] by 1, nums = [2,1,3] . - Increment nums[2..2] by 1, nums = [2,1,4] .
Constraints
1 <= nums.length == target.length <= 105
1 <= nums[i], target[i] <= 108
