Same for me ^^

lmao

Why you did not do that?Maybe someone like me learn something new from you :)

Semicolons are never needed, actually! Maybe I prefer my solutions as needless one-liners.

Semicolons are needed in some cases. I just prefer using them all the time.

A primitive iterator. pairs(table) returns next, table, nil, so pairs(table) is effectively identical to next, table.

Started out as a one liner, didn't expand because it wasn't necessary. At least I'm not using semicolons in Lua ;)

That is unnecessarily minimalistic.

What is "next"?

Thanks, my english is not very good)).

return the count of pairs that have consecutive numbers

These are the pairs for that input:

(21, 20), (22, 40), (39, -56), (30, -55), (95, 94)

Only two of those have consecutive numbers: (21, 20), (95, 94)

assertEquals(2,Solution.solve(new int[]{21, 20, 22, 40, 39, -56, 30, -55, 95, 94}));//
There is only one pair (22, 40) or am I wrong? Because of this, the solution does not pass.
