mediumArraysPattern: Array Transformations
Alternate Color Swapping Solution
Problem Statement
You have an array of integers that represents a sequence of alternating light blue and white squares on a wall...
Examples
Example 1:
Input:{"arr":[1,2,3,4,5],"k":2}
Output:[3,0,5,2,7]
Example 2:
Input:{"arr":[-1,0,1],"k":1}
Output:[0,-1,2]
Constraints
- The input array will have an even number of elements.
- The input array will always start and end with a light blue square (represented by 1).
Time: O(n) Space: O(1)
