I loved problem F

this shows that you are capable of reaching cm very soon. good luck

I observed that using one array of size 5000*5000 will be fine (takes about 195900 KB) but as soon as you u use two array of size 5000*5000 you will get MLE. This problem was tricky we get tle and mle check these two submission acc code mle code

thank you for sharing your approach

getting tle on test 9 for problem E help https://mirror.codeforces.com/contest/1649/submission/148661424

I really like the way D was made. It was easy but little trick at the same time. Thanks for this

Really man , what is this !! truly strange

Code chef is joke .. and what is the point of copying .. It's reflects how Indians are .

just subtract the bad ones from the total you will get the true position . than take %3 and print.

your are right

thanks for this..

you can feel of it when you see my submission in 1st every thing is same except I used modulo for every iteration which gives me straight TLE

and then when I don't apply in each iteration it takes 62 ms

bad code 111795934

good code 111799139

The idea of taking 3k,3K+1,3K+2 was very interesting.. thanks

I loved the question D..

thanks

he made the question and god knows the proof ..
