Please check test case 3, where number 7 is mistakenly skipped.

Peng Liu on 26 Apr 2016

Also, number 12 in test case 4 ...

James on 26 Apr 2016

In test case 2, if x=0, should the sequence be 1:22 or completely empty?

Peng Liu on 26 Apr 2016

@James: "If x = 0, integers that are the sums of any 2 or more consecutive previous elements should be omitted."

HH on 28 Apr 2016

@Peng, thank you for the great catch. An illusive issue with my reference solution disrupted test cases 3 and 4. Now fixed.
