Maximize difference between odd and even | Function to find maximum and minimum value of a number that can be obtained by rotating bits.
Stores the value of N.
Stores the maximum value.
Stores the minimum value.
If temp is odd.
Update the maximum and the minimum value.
If flag is 1 , then return the maximum value.
Otherwise , return the maximum value.
Function to find the maximum difference between the sum of odd and even - indexed array elements possible by rotating bits.
Stores the maximum difference.
Stores the sum of elements present at odd indices.
Stores the sum of elements present at even indices.
Traverse the given array.
If the index is even.
Update the caseOne.
Stores the maximum difference.
Stores the sum of elements placed at odd positions.
Stores the sum of elements placed at even positions.
Traverse the array.
If the index is even.
Update the caseTwo.
Return the maximum of caseOne and caseTwo.
