Secret Research

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 consecutive n 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 

4
78
7835
19078
944

Sample Output 

+
-
?
*

很水的, 我還以為是什麼語法判斷, 結果根本不是


#include <stdio.h>
#include <string.h>
int main() {
	int n, l;
	char s[10000];
	scanf("%d", &n);
	while(n--) {
		scanf("%s", s);
		l = strlen(s);
		if(s[l-1] == '5')
			puts("-");
		else if(s[0] == '9' && s[l-1] == '4')
			puts("*");
		else if(s[0] == '1' && l >= 3)
			puts("?");
		else
			puts("+");
	}
    return 0;
}
