Merge sort doubt

#1

code is fine but test case not passing
maybe constraints?

#2

added comments where code is updated

#3

i didnt get this… s+ (e-s)/2 will avoid overflow
how can we write in place of (s+e)/2

can you please tell?

#4

s+(e-s)/2
would expand to
(2*s+ e-s)/2
would furher simplify to
(s+e)/2
so both are the same things
its just that instead of adding we use a s+(e-s)/2 formula to avoid overflow

#5
