Write me a code to count pairs with odd Bitwise XOR that can be removed and replaced by their Bitwise OR and the other steps required given the following:
Count pairs with odd Bitwise XOR that can be removed and replaced by their Bitwise OR | Function to count the number of pairs required to be removed from the array and replaced by their Bitwise OR values.
Stores the count of even array elements.
Traverse the given array.
Increment the count of even array elements.
If the array contains at least one odd array element.
Otherwise , print 0.
Driver Code"
How can the above be solved in Python?
