在perl中的array数组中插入元素

Question

Suppose i have a hash as below:

my @A=( 1,2,[[ 1,2 ],[ 3,4,5 ]], [ 6,7,8 ]);

How do i insert an array in the third element of the array above? Third element here is an array of arrays and i want to insert an array [9,10].

how can do this?

Answer 1

Use push and a dereference ( @{...} ):

push @{ $A[2] }, [9, 10];

Note that there is no "hash" involved.
