Split each two-word string in a list, compare if same and count using Linq

Question

Is it possible to split each string (containing 2 words) in a list, then compare if both words are the same and count that occurrences using Linq? For example:

Let's say I have a list containing

list[0] = "bla bla";
list[1] = "bla heh";
list[2] = "heh heh";

The output of count should be 2 in this case.

my attempt so far:

var count = lst.Count(c => c.Split(.......)....

can't get past this.

Any help would be greatly appreciated.

Answer 1

list.Select(c => c.Split(' ')).Count(y => y.Length >= 2 && y[0] == y[1]);
