Its simple. Use double not float because you need precision for values as large as ${2}*{10}^{8}$.

See this TC-

100000000 100000000 100000000 100000000 99999999

Your Output
Correct Output

Determining what data type to use is the most fundamental concept which requires 100% accuracy. Be careful next time.

Also, next time, please give 2 minutes into indenting your code or adding proper comments. Its really painful for eyes to see an un-indented and uncommented code. Please think of the person going through your code to help you.

It is a basic segment tree problem with an insight.

this is exactly what I have done. it would be helpful if you could point out the mistake in my code

(09 Dec '17, 17:01) viralivora3★

i guess you should use ceil function for ceil( (max(L,R) - min(L,R))/2)

Also, refer this implementation of Segment tree for min-max queries

(09 Dec '17, 17:06) taran_14074★

but i did max((max(l,r)+min(l,r))/2,min(l,r)+max( max(0, L-1), max(R+1, N-1))) which is basically the same thing and hence does not require ceil function

I'm solving it myself..

it would be nice if u could point out error in my code,instead of solving it your self:)

Your segment tree is working fine..

Can't figure out what's wrong with your code... :(

My code with same approach gives AC
