Method 6: using a loop to iterate through the string and concatenate the characters with the separator. If a, Shekhar is an artist. Time complexity: O(n)Auxiliary Space: O(n). So, practice frequently with these simple java programs examples and excel in coding the complex logic. You could also use Python syntax, in which case your code would be: str (!FROM!) Remove the trailing separator from the result string. Example to split string by two delimiters import re target_string = "12,45,78,85-17-89" # 2 delimiter - and , # use OR (|) operator to combine two pattern result = re.split(r"-|,", target_string) print(result) # Output ['12', '45', '78', '85', '17', '89'] Run The opposite operation is .join(), so you call it on the string or character you want to use to join your iterable of strings together: Here, we join each element of the strings list with a comma (,) and call .join() on it rather than the strings list.
