Hi, I am trying to capitalize a word in a string

For example, the structionn tells you to capitalize the word 'Mello' and lowercase the word 'Hello'.

in = ['Hello Mello Jello Mello Hello']

I want to return this: in = 'hello MELLO Jello MELLO hello'

strrep() function is banned here..I need to used something else

Code is used to do repeatable tasks, according to rules. If you cannot tell us the exact rule to use, we cannot write code to do it.

Think about it. Suppose next time you tell me to convert "Hello" to "HeLLo" and "Mello" to "mELLO"?

It is impossible to write code for every possibility, for any input string. You need to be more specific.

"strrep() function is banned here". What about regexprep

in = 'Hello Mello Jello Mello Hello';
out = regexprep(in, {'hello', 'mello'}, {'hello', 'MELLO'}, 'ignorecase')

Result

out =
    'hello MELLO Jello MELLO hello'
