How do I use ">" and "<" inside "Cases" Mathematica function?

Question

How do I use ">" and "<" inside "Cases" Mathematica function?

E.g., I would like the cases which end in something greater than 2 for the following nested list:

    lst = { {1, 0, 0}, {1, 1, 1}, {1,1,4} }

I would like to do something like

    Cases[lst, {_, _,>2} ] 

What it is the correct way to express ">2" above?

Answer 1

The most straightforward fix to your approach is probably

Cases[lst, {_, _, x_ /; x > 2}]

See the documentation for /; or Condition.

Answer 2

Alternatively,

Cases[lst, {_, _, _?(# > 2 &)}]
