  This frame has 2 object(s):
    [32, 512) 'minus'
    [544, 664) 'stack' <== Memory access at offset 543 underflows this variable
HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext

SUMMARY: Addres

Your answer may be identical to the JOJ answer in the first several lines.

However, the main problem you meet now is Runtime Error. And the exit code of your program is 1, which should be 0.

Please double check your code to solve this problem and try again.
