Description

db = insert(da, key, value) adds the key-value pair to the dictionary da.

If the key already exists, its value is updated.

d = insert(d, key, value) is equivalent to d[key] = value.

db = insert(da, key, value, 'overwrite', tf) specifies whether to overwrite an existing value for the key based on the boolean parameter Overwrite.

Example

names = ["Apple" "Banana" "Kiwi"];
wheels = [1 2 3];
d = dictionary(wheels, names)
d = insert(d, [2 4] ,["Orange" "Citra"], 'Overwrite', false)
