Hello all,

After several years of escaping the CF plagiarism catcher, today I have finally been caught red-handed by the system.

It took a relatively long amount of time and I was wondering when it would happen.

I see a very long list of people on the message, probably not less than 100 people for problem C in today's round 852.

Here is my submission to C open to scrutiny by the CF community.

https://codeforces.com/contest/1793/submission/193309665

Now like every other defendant, I would like to plea for not being guilty of copying the solution (indeed I have no proof of such a thing but yeah)

Anyways it was a funny thing to happen so I decided to make the blog.

Your solution 193309665 for the problem 1793C significantly coincides with solutions chuchu/193292752, Alphx/193308147, weakestOsuPlayer_244/193309665, sam2001sahil/193316282, python_0098/193316695, harshmakwana22/193316697, im_into_cp/193317885, TheEliteCoder/193317894, OXYgen_ru/193318528, akshat_017/193319600, Tanay1234/193319916, _i_am_viper/193320720, ayushpratap344/193320868, rvdddddd/193320872, yoloo123/193320880,........

Hello everyone. I was trying to learn how GDB works and learn about debugging.

While trying to set breakpoint on main function I saw that it's not displaying the line number in decimal.

So I looked up a bit and found that one needs to include the -g flag while compiling the cpp file.

I did that and yet it doesn't show the line numbers in decimal. (Thereafter I tried to search this up but couldn't get the issue resolved)

My GDB version is 7.6.1 (probably latest for windows)

If someone can help me out with this it would be much appreciated.

UPD: Found out issue. Seems like compilation generates a separate file (a.out) and you have to run gdb on that file.

Hello guys.

I was trying the problem https://codeforces.com/contest/182/problem/D

The intended complexity of my solution is supposed to be $O(n\sqrt{n})$ but somehow I was repeatedly getting TLE. When I switched the concerned part where I was using + for concatenation of two strings with append it got accepted.

I went over to stackoverflow for figuring out the cause but I couldn't understand much of it besides trying the reserve keyword. I also tried using the reserve keyword for reserving space for the string but it resulted in TLE as well.

Here are my submissions:-

https://codeforces.com/contest/182/submission/82678284 -Using append.

https://codeforces.com/contest/182/submission/82677975 -Using + for concatenation.

While learning about segment tree I came across this problem:-

The task is as follows: for a given value x we have to quickly find smallest index i such that the sum of the first i elements of the array a[] is greater or equal to x (assuming that the array a[] only contains non-negative values).
