Address 0x7ffc3ea553b0 is located in stack of thread T0 at offset 176 in frame
    #0 0x514e0f  (/out/package/main+0x514e0f)

  This frame has 3 object(s):
    [32, 132) 'buffer'
    [176, 276) 'buffer2' <== Memory access at offset 176 is inside this variable
    [320, 324) 'n'
HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext
      (longjmp and C++ exceptions *are* supported)
SUMMARY: AddressSanitizer: bad-free (/out/p

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.
