Given a string s1, find all occurrences of the single quote character and replace them with two occurrences of the single quote character.
If there are n such occurrences in s1, then s2 will be n characters longer than s1.
This problem description would benefit from an example of the kind of input that could be expected (as well as the correct output).
Based on the description, I thought that I had to replace the string 'o'clock' with the string 'o''clock' (so making it usable in MATLAB.). And no, I did not manage to create input like that.
Instead, you want to replace every single quote with a double quote EXCEPT for the start-and-end quotes.
So 'o''clock' ==> 'o''''clock'
an example would make it clearer
I am not getting it .... Its always showing wrong
I've found no matter how many '''' I add, it will only show one additional.
My answers are coming correct in MATLAB 2017b but not on this site.
Matlab's version of backslash plague!
The intention was to make a correct preallocation and the fill it without needing to extend the string or reshuffle its content. It would be good to gain more insight into how the size is calculated. Criteria for evaluating code is not only code size but memory and time efficiency, and efficiency in writing and maintaining the code.
I look forward to discerning what that output really is supposed to be. Running into difficulty.
Whether the input is vector?
Test if two numbers have the same digits
Equal to their cube
convert matrix to single column
Create an index-powered vector
Given two strings, find the maximum overlap
Back and Forth Rows
Remove any row in which a NaN appears
