Problem in solving this question
@avnoorsingh488
if n will be even then answer will always be n/2
ex
-1 -3 -5 - 7 … -(n-1)
2 4 6 8 … n
if u will add corresponding terms ( i,e -1 + 2, -3 + 4 ,-5+6 so on ) then u will get n/2 ones thats why n/2 will be answer.
if n will be odd then n-1 will be even so answer for even part will be (n-1)/2 and last term will be negative so final answer will be (n-1)/2-n (-n because last term will be negative)
