== Title == Tiny
== Description == I made a compiler for a subset of C and compiled some code with it. Can you figure out what it does?
== Flag == IGCTF{CompilersAreFun}
== Files == Participants should receive the "challenge" file.
== Deployment == /
== Solution/Writeup == The binary can be decompiled with a program such as Ghidra. In Ghidra, a function "check_flag" can be found. The source code of this function will contain a large set of assignments to an array (by default in hex). Decoding this hex will yield the flag.
