Count digit in a given number 👐👐👐!!!!!!!!!!!!!!!!!
Example -
if given number -->
X = 7654;
result -> 4
X = 765;
result -> 3
X = 76;
result -> 2
public class CountDigit { public static void main(String[] args) { //count digits in a given number int x = 9876; int result =0; while(x>0) { x = x/10; result ++; } System.out.println("Total digit -> "+result); //in this case result will be 4
} }
Time complexity: θ(d)
where d is the number of the digit in the input number.
