question Educational Codeforces Round 76 (Rated for Div. 2) D-Yet Another Monster Killing Problem

my submission 69496905

I am not able to understand which test case is failing any testcase would be highly helpful ..

I have put the following conditions *if maximum power of hero is less than maximum power of monsters then directly print -1 and exit

*else answer exists we iterate throughout and we create the bst array which is as described in the editorial.Using which we check the 2 conditions :-

--->if maximum in a our range is greater than our hero's power then we break and add a count to our days

--->if we have reached the hero with highest endurance and have exhausted him too then we again break and add a count to our days

I believe this covers all the possibilities ..

please help me .

Thanks in Advance

EDIT -- Now it is working

GUYS IT IS NOW WORKING THE ERROR WAS THAT I HAD INCREMENTED THE INDEX OF HEROES ONLY BY 1 EACH TIME WHICH DID NOT COVER ALL THE CASES. I HAD TO INCREMENT THE INDEX OF HEROES TILL I FOUND ONE WITH HIGHER ENDURANCE.

THANKS A LOT EVERYONE FOR YOUR REPLIES.
