Move A Dictionary Value

You are given a dictionary d, a key src (guaranteed to be present in d), and a key dst.

Modify d in place so that:

• key dst is assigned the value currently stored at src (creating dst if it does not already exist, overwriting it if it does), and
• key src is then removed from the dictionary.

Return None. You may assume src and dst are different keys.

NOTE: This is a function-type question — you only write the function. Do not read input or print anything; a hidden checker calls your function and checks its return value.

Example

Arguments

{'a': 5, 'b': 2}
'a'
'b'

Returns

{'b': 5}
