Java Exercises: Compute the digit number of sum of two given integers
Java Basic: Exercise-212 with Solution
Write a Java program to compute the digit number of sum of two given integers.
Input:
Each test case consists of two non-negative integers a and b which are separated by a space in a line. 0 ≤ a, b ≤ 1,000,000
Pictorial Presentation:

Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public static void main(String[] args)
{
System.out.println("Input two integers(a b):");
Scanner stdIn = new Scanner(System.in);
int a = stdIn.nextInt();
int b = stdIn.nextInt();
int sum = a + b;
int count = 0;
while(sum != 0)
{
sum /= 10;
++count;
}
System.out.println("Digit number of sum of said two integers:");
System.out.println(count);
}
}
Sample Output:
Input two integers(a b): 13 25 Digit number of sum of said two integers: 2

Java: Anagrams
Generates all anagrams of a string.
public static List<String> anagrams(String input) { if (input.length() <= 2) { return input.length() == 2 ? Arrays.asList(input, input.substring(1) + input.substring(0, 1)) : Collections.singletonList(input); } return IntStream.range(0, input.length()) .mapToObj(i -> new SimpleEntry<>(i, input.substring(i, i + 1))) .flatMap(entry -> anagrams(input.substring(0, entry.getKey()) + input.substring(entry.getKey() + 1)) .stream() .map(s -> entry.getValue() + s)) .collect(Collectors.toList()); }
