#1

answer given in the exaple should be 4?

#2

See the input array is:
1 -1 2 1
and target value is: 4
so three indexes that bring sum equal to 4 are 1, 2 and 3. That is value: -1, 2 & 1
Sum of these three values will result in 2. Therefore answer will be 2

#3

The task is to return the sum of three integers in arr such that their sum is closest to target. if we select 1,2,1 then it will be 4 na?

#4

Yes my bad, answer will be 4 only as of 1,2 & 1. Might have been mistake by problem setter.
