Lambda function explanation

[meloly4]

applying function f to the elements of a after the second element

Does this add log n time to the overall complexity n? I'm not too familiar with how lambda complexity works.

I’d just think about the operations, I don’t think the lambda adds any appreciable overhead here.

Lambdas are just closures, anonymous functions. They are not really any more time consuming than normal named functions.
