 To separate the part of a string where it is all upper case, you can use regular expressions in most programming languages.

Here is an example of Python code to extract the uppercase substrings:

Python

Copy code

import re

string = "HELLO WORLD I AM HERE"

uppercase_substrings = re.findall(r'\b[A-Z]+\b', string)

print(uppercase_substrings)

The regular expression \b[A-Z]+\b matches any substring that contains only uppercase letters and is delimited by word boundaries (i.e., spaces, punctuation, or the beginning/end of the string). The re.findall() function returns a list of all non-overlapping matches.

The output of the above code will be:

Copy code

['HELLO', 'WORLD', 'I', 'AM', 'HERE']

You can modify the regular expression to fit the specific needs of your string.
