C语言相关的练习断手之作

Question

真不会写（写了一天结果不对，哭了）（编是编好了，但结果很奇怪，然后我的变量命名和代码太乱了，就不发了）

这是题目给的密钥：

unsigned char password[70]={71,114,101,97,116,32,105,100,101,97,108,32,98,117,116,32,116,104,114,111,117,103,104,32,115,101,108,102,108,101,115,115,32,115,116,114,117,103,103,108,101,32,97,110,100,32,115,97,99,114,105,102,105,99,101,32,116,111,32,97,99,104,105,101,118,101,46};`

这是例子：

//输入
9 23 19 132 6 192 6 27 10 15 13 94 29 14 3 69 4 17 29 18 73 18 24 78
201 172 222 239 206 5 254 237 221 207 172 20 252 61 206 188 21 175 253 254 68 190 126 215

//输出
78 101 118 101 114 32 103 111 110 110 97 32 103 105 118 101 32 121 111 117 32 117 112 46
