Answer / suren

its simple for guys 4m Engineering background.
if u have an idea with series of numbers, (n(n+1)/2)

first take the sum of all the objects in array, next
subtrat the sum of arrays after deletion of object. this
will give you the deleted object value.

1,2,3... 10; sum = 10(10+1)/2=55

suppose the value of object deleted is 6;

then sum of the array after deletion will be 49;

55-49=6 ANS:
