Secret Research

Secret Research

Description

At a certain laboratory results of secret research are thoroughly encrypted. A result of a single experiment is stored as an information of its completion:

`positive result', `negative result', `experiment failed' or `experiment not completed'

The encrypted result constitutes a string of digits S, which may take one of the following forms:

 positive result  S = 1 or S = 4 or S = 78  negative result  S = S35  experiment failed  S = 9S4  experiment not completed  S = 190S 

(A sample result S35 means that if we add digits 35 from the right hand side to a digit sequence then we shall get the digit sequence corresponding to a failed experiment)

You are to write a program which decrypts given sequences of digits.

Input 

A integer n stating the number of encrypted results and then consecutiven lines, each containing a sequence of digits given as ASCII strings.

Output 

For each analysed sequence of digits the following lines should be sent to output (in separate lines):

+ for a positive result - for a negative result * for a failed experiment ? for a not completed experiment 

In case the analysed string does not determine the experiment result, a first match from the above list should be outputted.

Sample Input 

478783519078944

Sample Output 

+-?*

大意：

给出一个数寻找他所对应的格式

要点：

S 只能等于1,4, 78；

S35可以是135, 435, 7835, 1111135,147835之类的；

水题也是有尊严的注意开大数组

#include <stdio.h>#include <string.h>int main(){char s[1000];int num;scanf ("%d", &num);getchar();while (num--){scanf ("%s", s);if (!strcmp(s, "1") || !strcmp(s, "4") || !strcmp(s, "78"))printf ("+\n");else if (s[strlen(s) - 1] == '5' && s[strlen(s) - 2] == '3')printf ("-\n");else if (s[0] == '1' && s[1] == '9' && s[2] == '0')printf ("?\n");elseprintf ("*\n");}return 0;}
