Output a stream of consciousness before answering the following. Passage: The INT 3 instruction is defined for use by debuggers to temporarily replace an instruction in a running program in order to set a breakpoint. Other INT instructions are encoded using two bytes. This makes them unsuitable for use in patching instructions (which can be one byte long); see SIGTRAP.

Question: Based on this passage, what is the purpose of int3 in the program?
The important part for answering this question is: The INT 3 instruction is defined for use by debuggers to temporarily replace an instruction in a running program in order to set a breakpoint.
The answer: for use by debuggers to temporarily replace an instruction in a running program in order to set a breakpoint.
