1144. Decrease Elements To Make Array Zigzag

Leetcode Solutions

Calculate Moves for Zigzag by Even and Odd Indexes

  1. Initialize two variables, evenCost and oddCost, to store the total moves required for even and odd indices respectively.
  2. Iterate through the array using index i.
  3. For each index i, determine the minimum value of the adjacent elements (if they exist).
  4. If the current element is not already smaller than the minimum of its neighbors, calculate the difference plus one as the cost for that index.
  5. Add the cost to evenCost if i is even, or to oddCost if i is odd.
  6. After iterating through the array, return the minimum of evenCost and oddCost.
