Answer Posted / kiruthikau
$array[1] represents a scalar value.
@array[1] represents array slicing.
@array[1] returns a list with one scalar value.
We should use $ when we want a scalar value.
If we want a list we need to use @.
If we use 'use warnings' then @array[1] will give the warnings
like ,Scalar value @array[1] better written as $array[1].
