Function Name: mealPrep()

Inputs: 1. (char) A 1 x N char vector containing a message

Outputs: 1. (char) a 1X N char vector of the decoded sentence

Topics: (char vectors),(LHS/ RHS indexing), (colon operator), (strfind/strrep), (casting)

Function Description: Given a character vector containing a message, follow these steps in the correct order to decipher it:

1. Starting with the first index of the char vector, shift every third index up 2 ASCII values (for example,'q' 's')

2. Replace all underscores '_' with a single space

3. Capitalize the first letter of every word in the sentence

Example: mixed = 'qalr_tfe_uatcr_`efmre]boglilg_gt'

fixed = mealPrep(mixed)

fixed 'Salt The Water Before Boiling It'

Notes: Make sure to capitalize the first letter of every word, including the first word (step 3)

Words will be separated by a single underscore

The original statement may contain special characters, but shifting should remove all special characters (except underscores), and the final output should not contain any

Hints: You may need to cast the char vector to a different data type to perform a mathematical "shift" for step 1

The letters at the beginning of a word are always one index after a space except for the very first character of the string

The colon operator may be useful
