GATE CSE 1987 | Question: 6a
A list of $n$ elements is commonly written as a sequence of $n$ elements enclosed in a pair of square brackets. For example. $[10, 20, 30]$ is a list of three elements and $[]$ is a nil list. Five functions are defined below: $car (l)$ returns the first element of its argument ... $f ([32, 16, 8], [9, 11, 12])$ $g ([5, 1, 8, 9])$
