Clashing with AtCoder Beginner Contest 216 :(

How come is it that every time starters end up clashing with ABC even though the target audience for both contests are similar. I mean Atcoder hosts ABC every weekend so you should at least check for clash beforehand after it was brought to your notice for the first time.

Utkarsh.25dec :orz:

Number of problems in each division? Utkarsh.25dec

In Magical Flips Problem i print cout<<cnt<<' '<<ans<<endl; instead of cout<<ans<<' '<<cnt<<endl;

But its magically passed sample. got that after 2 WA and 12 min penalty tho xD

the submissions of div2C started increasing so rapidly.:(

Div 2 C

Some guy posted a solution in a "famous for cheating telegram group" and the count of submissions rose to 1000+ from 250 in just 15 minutes.

Utkarsh.25dec, nishant403, infinitepro, satyam343 please have a plag check!

This person is literally revealing the solution of problem A,B,C of div2 on Youtube

His youtube account

And his codechef ID

Link he give during the contest of problem C and you can easily see that last most of submission of this problem is totally same as in the given link,

Before half hour of contest end my rank is about 700 and suddenly just after 15 minutes my rank was 1500. This is really disgusting. Due to these cheaters our rank does't give confidence to Newbies like me. I hope it will change in future,

In Div2 D ( Grid Path ) I started of with submitting a recursion+memorization code ( O(n*n*k) ).. but it TLed at one of the testcase [ I also included the snippet to increase stack memory ]

But writing the same logic iteratively, it passed with (0.18 time).. Though i know that recursive+memo is comparatively slow but never knew it was this slow..

Is this the general case or there's something different with codechef testing system only ??

problem .Grid Path in div2..how can i approach this?.any hint..
