该方法是一种用于检查数组中两个整数是否重合的算法,可以通过将整数移位来查询它们存储在数组中的位置。
%
。+
。arr[(A % N + N) % N]
和 arr[(B % N + N) % N]
。def check_overlap(arr, A, B, N):
"""
Check if two integers A and B overlap in an array arr of size N
"""
index_A = arr[(A % N + N) % N]
index_B = arr[(B % N + N) % N]
if index_A == index_B:
return True
else:
return False
arr = [1, 2, 3, 4, 5]
N = 5
A = 1
B = 6
if check_overlap(arr, A, B, N):
print("A and B overlap in the array")
else:
print("A and B do not overlap in the array")
运行示例代码将输出 A and B overlap in the array
,因为在数组中,arr[1]
和 arr[6 % 5]
的值相同,即都是 2
