Write a program to get number of 2's present between 0 and given number N including N.

Input (int) Output (int)
12 [2], 1[2] = 2
112 [2], 1[2], [2]0, [2]1, [2][2], [2]3, [2]4, [2]5, [2]6, [2]7, [2]8, [2]9, 3[2], 4[2], 5[2], 6[2], 7[2], 8[2], 9[2], 10[2], 11[2] = 22

``` class CountNumberOfTwos {     public static void main(String s[])    {        int number = 222;        System.out.println("Number of 2's present between zero and " + number + " are " + getTwosCount(number));    }     public static int getTwosCount(int number) { ```
```     } } ```

As per the question we need to count the numbers which contain 2 in it from 0 to input number... For that we need to take a count variable for counting the number which contain 2... Take a loop that iterates until 0 to input... Inside the loop take another loop which will get the remainder of number until number becomes 0.. In inner loop if we find 2 in any position then increment the count variable...

here we have two count twos in a given range... so frstly initialize count =0 .take a=2 to input... now inside this loop s=a, take loop while(s>0) {  b=s%10 s=s/10 .....if b==2 then. increment count by one..}} exit both loop... primt count.
