Labview string to array conversion problem

Write a program to determine whether the lowercase letters in the input control are arranged in ascending order of abcd...xyz? If so, output True, otherwise, output False.

For example, if the input string is acde, the output is True because the four letters a, c, d, and e are arranged in ascending order. If the input string is adb, the output is False because the three letters a, d, and b are not arranged in ascending order. The same goes for other functions.

My idea for this question is to convert the string into an array, use the array's one-digit array sorting control to sort it in ascending order, convert it into an array, and then compare the strings before and after the sorting.

After the difficult string is converted to an array, it will have its own line breaks, so you need to use a one-dimensional array search to find the end of the string, and then split the one-dimensional array to take only the useful parts for sorting.
