Minimum increments required to make array elements alternately even and odd | Function to find the minimum number of increments required to make the array even - odd alternately or vice - versa.
Store the minimum number of increments required.
Traverse the array arr [ ].
Increment forEven if even element is present at an odd index.
Increment forEven if odd element is present at an even index.
Return the minimum number of increments.
