class Solution:
def decrypt(self, code: List[int], k: int) -> List[int]:
# Circular array sum with sliding window
# Time: O(n), Space: O(n)
n = len(code)
result = [0] * n
if k == 0:
return result
# Double the array for circular handling
doubled = code + code
if k > 0:
# Sum next k elements
for i in range(n):
result[i] = sum(doubled[i+1:i+1+k])
else:
# Sum previous |k| elements
k = -k
for i in range(n):
result[i] = sum(doubled[n+i-k:n+i])
return result
