Some test cases not passing

#1

Hi!
I’m not getting my mistake. Please help

#2

hello @sukritbansal01

	for(int i=0; i<a.size()-1; i++){
		if(a[i+1].first<=a[i].second){
			ans++;
			
		}
	}

this comparison is wrong.
here u need to compare current circle i with last circle that u have included in ur answer.
but here u r always comparing consecutive circle

I’m no able to get that how the 2 approaches are different. Also, by using below method, I’m getting wrong answer.

#4

for(int i=1; i<a.size(); i++){ if(a[i].first<=a[i-1].second){ ans++; } }
