Re: What wrong in this code?

It was thus said that the Great Jorge Eduardo de Araújo Oliveira once stated:

  Problem 1: lua-53: y.lua:11: attempt to index a nil value (global 'is')
stack traceback:
        y.lua:11: in main chunk
        [C]: in ?

  Problem 2: lua-53: y.lua:16: bad argument #1 to 'concat' (table expected, got nil)
stack traceback:
        [C]: in function 'table.concat'
        y.lua:16: in main chunk
        [C]: in ?

  Problem 3: lua-53: y.lua:22: attempt to call a nil value (global 'buscaLinear')
stack traceback:
        y.lua:22: in main chunk
        [C]: in ?

  Quite a few typos ("is" instead of "os", "vector" instead of "array",
"buscalLinear" instead of "linearSearch").
