解题思路:

注意事项:

参考代码:

n,a,b = map(int,input().strip().split())

for i in range(n):

    print("(%d,%d)" % (a,i+1),end=" ")

print()

for i in range(n):

    print("(%d,%d)" % (i+1,b),end=" ")

print()

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

    for j in range(1,n+1):

        if i-j == a-b:

            print("(%d,%d)" % (i,j),end=" ")

print()

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

    for j in range(1,n+1):

        if i+j == a+b:

            print("(%d,%d)" % (j,i),end=" ")

print()
