can we change line 18 where element of array is compared with undefined?

@chhaviteotia in this problem we are checking whether the number is occurring first time or its already occurred, so for solving that kind of problem, we need to use undefined

@LVSsandeepVarma yes i can write the code in O(1) space, but this question belongs to topic ARRAY, so that's the reason why, i have used Array in the code, do you want me to do in O(1) space, without using any array?

@SaivijayK ok in that case then it's better with array only
