Hello Codeforces! I can't understand, why this code (278037374) has WA2 in problem 2004B - Game with Doors

I will be very grateful for any help!

Have a nice summer day

UPD: swaymbhu, thank you very much for answering question!

Assume case where l=1 and r=3 L=50 and R=70 your ans will never be incremented bcz at i(running from 0 to 100) ------equal to 3 it will be zero as v[2]=1 and v[3]=0 ------similarly at i=49 v[49]=0 and v[50]=1 so final ans=0 in any case answer is never less than 1

---ALL IN ALL JUST PUT THIS STATEMENT ans=max(1,ans);
