邻居坐标

  • 772

对于 M × N 表中坐标为 (x, y) 的单元格，打印其邻居的坐标。具有共同边的单元称为邻居。给出了自然数 M、N、x、y。以任意顺序将该单元格的邻居的坐标对输出到输出文件中。

出于某种原因，它给出了 0 分，尽管我用数字代替了，就像答案是正确的一样。

M, N, x, y = int(input()), int(input()), int(input()), int(input())

if M != 1 and N != 1:
    if x == 1 and y == 1:
        print(x + 1, y)
        print(x, y + 1)
    elif x == 1 and y == N:
        print(x + 1, y)
        print(x, y - 1)
    elif x == M and y == 1:
        print(x - 1, y)
        print(x, y + 1)
    elif x == M and y == N:
        print(x - 1, y)
        print(x, y - 1)
    elif x == 1:
        print(x + 1, y)
        print(x, y + 1)
        print(x, y - 1)
    elif x == M:
        print(x - 1, y)
        print(x, y + 1)
        print(x, y - 1)
    elif y == 1:
        print(x - 1, y)
        print(x, y + 1)
        print(x + 1, y)
    elif y == N:
        print(x - 1, y)
        print(x, y - 1)
        print(x + 1, y)
    else:
        print(x - 1, y)
        print(x + 1, y)
        print(x, y + 1)
        print(x, y - 1)

else:
    if M == 1 and N != 1:
        if y == 1:
            print(x, y + 1)
        elif y == N:
            print(x, y - 1)
        else:
            print(x, y + 1)
            print(x, y - 1)
    elif N == 1 and M != 1:
        if x == 1:
            print(x + 1, y)
        elif x == M:
            print(x - 1, y)
        else:
            print(x + 1, y)
            print(x - 1, y)

  1. 也许是这样的。让我们制作一张带有一组坐标变化的表格。我们将显示那些没有超出矩阵的

    M, N, x, y =  3, 3 ,2, 2 # 2 1 1 2 2 3 3 2
for i,j in [(0,-1),(-1,0),(0,1),(1,0)]:
        if 1<=x+i<M+1 and 1<=y+j<N+1:
            print (x+i, y+j)

    然后让我们打开我的循环，把它变成一个线性记录

    if 1<=x<M+1 and 1<=y-1<N+1:
   print (x, y-1)
if 1<=x-1<M+1 and 1<=y<N+1:
   print (x-1, y)
if 1<=x<M+1 and 1<=y+1<N+1:
   print (x, y+1)
if 1<=x-1<M+1 and 1<=y+j<N+1:
   print (x+1, y)

  2. Best Answer
    M, N, x, y = int(input()), int(input()), int(input()), int(input())

if N > 1:
    if y == 1:
        print(x, y + 1)
    elif y == N:
        print(x, y - 1)
    else:
        print(x, y - 1)
        print(x, y + 1)
if M > 1:
    if x == 1:
        print(x + 1, y)
    elif x == M:
        print(x - 1, y)
    else:
        print(x - 1, y)
        print(x + 1, y)

    根据您的输入：

    N: 3
M: 3
x: 2
y: 2
...
2 1
2 3
1 2
3 2
