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 = 23 or S = 2S3
negative result S = 51S
experiment failed S = 5S
experiment not completed S = 2S1 or S = 24S

(A sample result 51S means that if we add digits 51 from the left 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
