/in/lab5.c:250:22: runtime error: index -1 out of bounds for type 'int [120]'

Address 0x7ffe15461eec is located in stack of thread T0 at offset 92 in frame
    #0 0x5602795ad07f in in2po (/out/package/lab5+0x607f)

  This frame has 3 object(s):
    [32, 36) 'top'
    [96, 576) 'stack' <== Memory access at offset 92 underflows this variable
    [608, 623) 'varname'
HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext
      (longjmp and C++ exceptions *are* sup

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.
