Exit code 131312
By Ny0n, 11 months ago, In English

My submission 243855915 for 1925A exited with the code 13131312 on test case 2. I couldn't find any details online on this specific code. Any idea what might be causing this?

Do this

string res = s;
FOR(i,n-1)res+=s;
cout<<res<<ln;

as for why s += s is not working. use the input 4 4 you'll see what is going wrong and somewhat like 26 26 will give the runtime

    Oh Thanks!

    My bad, should've noticed the problem with s+=s.

Looks like this exceeds some internal limit on the output size (~50 megabytes?) before anything else.

    Indeed, I get bad_alloc when I run it with 26 26 in my local ide.

    Still, I'm kinda curious about the error code which was generated.

      This code occurs when some of the judge's internal limit is hit.

while you run s+=s it will increase your initial set of character exponential time, for example, 3,4:-Initial s="abcd' then s+=s gives s='abcdabcd' i.e., two times of original s, again after s+=s gives s='abcdabcdabcdabcd' i.e., 4 times of the original s but we need only 3 times of original s. so, use temporary_var=s for the first time and then, loop for (i, n) s+=temporary_var. if you use python you can do this in one line s=s*n or s*=n. I hope you understand the error.
