Data Engineer

• What are joins?
• Explain all types of keys
• Define normalisation and kinds of normalised forms.

You are given an array of positive integers, ‘NUMS’, and provided with an integer ‘K’. Your take is to find out whether it is possible to find two distinct elements of ‘NUMS’ whose sum is equal to ‘K’.

By distinct we mean the index of the elements should be distinct, not necessarily their value.

You are given an array 'ARR' of the 'N' element. Your task is to find the maximum difference between any of the two elements from 'ARR'.

If the maximum difference is even print “EVEN” without quotes. If the maximum difference is odd print “ODD” without quotes.

For example:

Given 'ARR' = [1, 10, 5, 2, 8, 1 ] , answer is "ODD".
Here the maximum difference is between 10 and 1, 10 - 1 = 9
