What is a code to bitwise operations on Subarrays of size K and the other steps required given the following:
Bitwise operations on Subarrays of size K | Function to find the minimum XOR of the subarray of size K.
K must be smaller than or equal to n.
Initialize the beginning index of result.
Compute XOR sum of first subarray of size K.
Initialize minimum XOR sum as current xor.
Traverse from ( k + 1 ) ' th ▁ ▁ element ▁ to ▁ n ' th element.
XOR with current item and first item of previous subarray.
Update result if needed.
Print the minimum XOR.
Driver Code.
Given array arr.
Given subarray size K.
Function call"
How can the above be solved in Python?
