Good job @KiwookShim :) 
but this code is a little wrong.

If you wanted to remove `start` from ['cmd', '/c', 'start'], then it should use `info.splice(2,1)`.
And  `splice()` return value means `Deleted array` so, if you want to get [`cmd', '/c'], then just use 'info.splice(2,1)` instead of `info = info.splice(2,1)`.

I'm outside now, so I can't run this code, but what I mentioned may be right. :)
