参考代码:

high, wide, s, flag = map(str, input().split())
for i in range(int(high)):
    for j in range(int(wide)):
        if flag == '0':
            if i == 0 or i == int(high)-1:
                print(s, end='')
            else:
                if j == 0 or j == int(wide)-1:
                    print(s, end='')
                else:
                    print(' ',end='')
        else:
            print(s,end='')
    print()
