Let us say if I have a hash like this:
$data = {
'key1' => {
'key2' => 'value1'
},
'key3' => {
'key4' => {
'key5' => 'value2'
}
},
};
Now, how can I replace the the key 'key5' with some other key name say 'key6'? I know how to loop through the hash & dump the values but I don't know how to replace keys or values in place. Thanks for your help.
