Using aforloop with aStringBuilderprovides a straightforward approach to removing digits from aString. This method involves iterating over eachCharacterin theString, checking if it’s a digit, and then appending non-digitCharactersto aStringBuilder: @TestvoidwhenUsingForLoop_thenGetExpectedResult(){Str...
We will iterate the string using the for loop and then we will check whether each character is a digit or not using if statement, if it is a digit then we will go to next character, otherwise we will replace that character. For iterating repeatedly through a sequence, use a for loop....
Well, one can simply scan from left to right, and remove the first "peak" digit; the peak digit is larger than its right neighbor. One can repeat this procedure k times, and obtain the first algorithm: stringremoveKdigits(stringnum,intk) {while(k >0) {intn =num.size();inti =0;w...
publicclassSolution { publicString removeKdigits(String num,intk) { intlen = num.length(); //corner case if(k==len) return"0"; Stack<Character> stack =newStack<>(); inti =0; while(i<num.length()){ //whenever meet a digit which is less than the previous digit, discard the previ...

For thisexample, let’s say we want to remove the hyphen (-) from the ZIP+4 format to make it a continuous 9-digit number. zip_code = "12345-6789" new_zip = zip_code[:5] + zip_code[6:] print(new_zip) Output:In this Python string, the hyphen is at the5th position(remember...
Repeat these b,c steps for all elements of the string. 4)Remove all ‘*’ from the string as follows. for loop iterates through the string until s[i] becomes to null, with the structure for(i=0;s[i];i++). a)initialize s[i]=s[i+k] ...
the general idea is: we know that digts on the left side matters, so we use a stack and push each of chars in that stack. whenever meet a digit which is less than the previous digit, discard the previous one. so that means we will use stack to maintain a increasing sequence. ...
# Remove all non-numeric characters from a String using join() This is a three-step process: Use a generator expression to iterate over the string. Use the str.isdigit() character to check if each character is a digit. Use the str.join() method to join the digits into a string. main...
You can also use this formula to remove more than one digit. Note: This method can only remove the last digit from a numeric dataset. If you have a text dataset, you won’t be able to use it (as you can’t divide a text string by 10) ...
