wish of those help You can use componentsSeparatedByCharactersInSet: to get the effect that you are looking for: code :
-(NSArray*)parseString:(NSString *)inputString {
return [inputString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];

 Creating an array of all substrings of a string

To fix the issue you can do This is similar to generating permutations given a number "N". So find the length of the string first and iterate and generate the substrings Something like this- code :
Algorithm-
for i=0 to string.length
for j=1 to string.length-i
//Generate substrings here

 Creating an exhaustive list of `n` substrings

Does that help I am training to split a string into n substrings and return a list of tuples of them. , Here is one way to do this, recursively, using a generator: code :
def split_str(s, n):
if n == 1:
yield (s,)
else:
for i in range(len(s)):
left, right = s[:i], s[i:]
for substrings in split_str(right, n - 1):
yield (left,) + substrings
for substrings in split_str('house', 3):
print substrings
('', '', 'house')
('', 'h', 'ouse')
('', 'ho', 'use')
('', 'hou', 'se')
('', 'hous', 'e')
('h', '', 'ouse')
('h', 'o', 'use')
('h', 'ou', 'se')
('h', 'ous', 'e')
('ho', '', 'use')
('ho', 'u', 'se')
('ho', 'us', 'e')
('hou', '', 'se')
('hou', 's', 'e')
('hous', '', 'e')
for i in range(1, len(s) - n + 2):

 Creating new rows for listed substrings

it fixes the issue My goal is to create a wordcloud in R, but I'm working with nested JSON data (which also happens to be incredibly messy). , You can use separate_rows from the tidyr package: code :
library(tidyverse)
data %>%
separate_rows(listcites, sep = ",") %>% # split on commas
dmap_at("listcites", ~ gsub("^c\\(\"|\")$|\"", "", .x)) # clean up the quotations and parens

Creating substrings array from a string

seems to work fine I have a string that has no spaces and I wanted to create an array that consists of the substrings of the word. For instance, let the string is stackoverflow The array should be like: , There are two issues with your code. First, the "3" in code :
s.substring(i, 3)
s.substring(i, i + 3)
public static ArrayList<String> getWords(String s){
ArrayList<String> words = new ArrayList<String>();
for(int i=0;i<s.length(); i=i+3){
words.add(s.substring(i, Math.min(i + 3, i.length())));
}
return words;
