We can useJava Regular Expressionstocount the number of matchesfor a digit. In regular expressions,“\d“matches “any single digit”. Let’s use this expression to count digits in a string: int countDigits(String stringToSearch) { Pattern digitRegex = Pattern.compile("\\d"); Matcher coun...
Si = Si - 1 + "1" + reverse(invert(Si - 1)) for i > 1 Where + denotes the concatenation operation, reverse(x) returns the reversed string x, and invert(x) inverts all the bits in x (0 changes to 1 and 1 changes to 0). For example, the first four strings in the above s...

Approach-1: By Using Simple Digit Check Method In this approach, we declare an array with some random integer values and by using our algorithm we find the single digit number and print those numbers as output. Example Open Compiler public class Main { public static void main (String[] args...
