# License
## Description
Description: Keith made a cool license-checking program but he forgot the flag he used to create the key! To make matters worse, he lost the source code and stripped the binary for his license-generator program. Can you help Keith recover his flag? All he knows is:*	The license key is 4-EZF2M-7O5F4-V9P7O-EVFDP-E4VDO-O*	He put his name (in the form of 'k3ith') as the first part of the flag*	There are 3 underscores*	The flag is in the format hsctf{}*	The flag doesn't have random character sequences (you should be able to read the entire flag easily).*	The flag only contains lowercase English letters and numbers.*	The generator might produce the same keys for different inputs because Keith was too lazy to write the algorithm properly.

## Solution
Input ```a..z0..9``` and find the characters one by one.

The flag is
```hsctf{k3ith_m4k3s_tr4sh_r3}```
