I think something is wrong

    W

    input [0,0,4] and 4
    I believe the answer should be [1,3], but in fact the giving answer is [2,3].
    I think before we put the value into the hash table, we should check whether it has been exist.

    I think it depends on the sequence you put the objects pair to hashtable and the loop sequene of searching.

    Quote from the problem page:

    "You may assume that each input would have exactly one solution."

    So your input is invalid.

    A

    Exactly !

    I have completed my code and it's working for valid inputs. But, I am facing a hard time submitting it. On submitting the code, it says that my code gives out a wrong answer for the input.
    [0, 4, 3, 0]
    0

    I fail to understand why such input is being used here when the question mentions "You may assume that each input would have exactly one solution."

    Any ideas on where should I report this ?

    Thanks in advance.

    [0, 4, 3, 0] 0 is valid. There is only one solution.
