Use the inbuilt replaceAll() method of the String class which accepts two parameters, a Regular Expression, and a Replacement String. To remove the leading zeros, pass a Regex as the first parameter and empty string as the second parameter. This method replaces the matched value with the given string.
Using Stoi() Method stoi() function in C++ is used to convert the given string into an integer value. It takes a string as an argument and returns its value in integer form. We can simply use this method to convert our string to an integer value which will remove the leading zeros.
Use str.strip(chars) on a string with "0" as chars to remove zeros from the beginning and end of the string.
I have strings like this:
var abc = "002";
var def = "023";
How can I easily change the strings so the leading zeros are dropped?
