how can be solved using Meet in the middle ?

yes exactly :'''''(

MikeMirzayanov can you help me :( ?? I still didn't solved the issue

you wanna count all pair such that their product is below their G to validate whether G is the answer or not.

I think you've forgotten to multiply by the depth , am I wrong :/ ?

so you should write N^4

wow! , your solution is very interesting thanks <3 !!!

finally AC , Big Thanks IgorSmirnov , you're great debugger by the way :)

I'm sorry tooo :(( , but i went to WA on test case 6 lool here

I think nope :/ because i compare two strings with each others so i used lst = i (the first position before the beginning of the last string) so i am getting its end with lst + size

Ohh I thought that this operation works in O(1) but you made it clear to me :)

but there's another mistake somewhere :''( , I got WA on test case 5 too

Here

guys i still struggling to get AC :( , if someone can help me

I got WA on test case 5 and my solution works in O(|Needed String|)

Here

yes :/

IgorSmirnov can you help me :/ ?

I got WA on test case 5 while my algorithm works in linear time O(|Size of needed string|) that's good enough

Here

WHEN YOU FOUND A SOLUTION FOR PROBLEM B AND CODEFORCES SAYS TO YOU "CONTEST IS OVER"

tourist again :( !

try this site 100 % math problems https://projecteuler.net/

Thanks :) !

i think so :/ , but i need to change my rating :"(

I wish the time of the contest will be any time instead of breakfast time for muslims people in ramadan :/ , there is many contest in this time , can any one who will create a new contest can make it any time but not in our breakfast time ?, i think there is many Programmers will join it
