string modifying methods

Method	Description	Examples	Results
`replace('a', 'b')`	Replaces all the occurrences of `a` with `b`	`'Abcde'.replace('A', 'B')` `'ABBA'.replace('A', 'B')` `'ABBA'.replace('AB', 'C')`	`Bbcde` `BBBB` `CBA`
`strip()`	Removes whitespace from both ends	`' Hi Bob '.strip()`	`Hi Bob`
`lstrip()`	Removes whitespace from the beginning	`' Hi Bob '.lstrip()`	`Hi Bob`
`rstrip()`	Removes whitespace from the end	`' Hi Bob '.rstrip()`	`Hi Bob`
`removeprefix('a')`	Removes the specified prefix if it’s present	`'Hi Bob!'.removeprefix('Hi')` `'Hi Bob!'.removeprefix('hi')`	`Bob!` `Hi Bob!`
`removesuffix('a')`	Removes the specified suffix if it’s present	`'Hi Bob!'.removesuffix('!')` `'Hi Bob?'.removesuffix('!')`	`Hi Bob` `Hi Bob?`

The methods replace and strip are very popular and are used pretty often in real-life programs.

Challenge

Each gene's code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). We don’t like abbreviations, so we would like to expand these abstractions any time we find those in the text. Given a text with abstractions including A, C, G, and T, expand those into their actual names.

The input contains a single line with text with abbreviations.

The program should print the same text with expanded abstractions in the output.
