感谢题解的启发，想了半天了都

解题思路:

注意事项:

参考代码:

n,i,j=map(int,input().split())

for q in range(1,n+1):

    print(f"({i},{q})",end=" ")

print("")

for q in range(1,n+1):

    print(f"({q},{j})",end=" ")

print("")

for m in range(1,n+1):

    for w in range(1,n+1):

        if m-w==i-j:

            print(f"({m},{w})",end=" ")

print("")

for m in range(1,n+1):

    for w in range(1,n+1):

        if m+w==i+j:

            print(f"({w},{m})",end=" ")
