Classic 3-SUM problem.

Also your input is invalid in the 2nd example. N=4 and then you provide only 3 more lines, one of which is supposed to be the result. If N=4 then I would expect 5 more lines.

sorry for the invalid input.
The 2nd input:
4
1
3
12
4
14
output:
false.

Explanation for sample input and output 2:
since no combination of given beverage size um up to X i.e. 14, the output will be False.
Explanation for sample input and output 1:
The sum of 2nd,5th and 6th beverage size is equal to 22.So the o/p will be True.

k-sum problem.
Complexity would be O(n^(k - 1)).
