0 and 1 values, along with an integer k.1 values found in any run of k consecutive circular positions.k > n is handled, since the result differs depending on whether multiple trips around the circle are permitted.def max_ones_in_circular_subarray(arr, k, allow_repeated_wrap):
arr = [1, 0, 1, 1, 0], k = 3, allow_repeated_wrap = False
2
The maximum is 2; four of the five length-three circular windows contain two 1s.
arr = [0, 1, 0, 1], k = 2, allow_repeated_wrap = False
1
Each pair of neighboring circular positions includes exactly one 1.
Input: arr = [1, 1, 0], k = 5, allow_repeated_wrap = True
Output: 4
Explanation: Repeated wrapping allows the length-five window [1, 1, 0, 1, 1], which has four 1s.
k=1, k=n, sequences containing only zeros, sequences containing only ones, and a best window that crosses the array boundary.
