Find Number of Numbers

Problem Statement:

Given an array A[] of n elements. Your task is to write such program which returns an integer denoting the total number of times digit k appears in the whole array.

For Example:

A[]={11,12,13,14,15}, k=1

Output=6 //Count of the digit 1 in the array

Prerequisite:

MATLAB CODE FOR THIS PROGRAMME:

clc

x=input('Enter the array:');

k=input('Enter the number:');

c=0;

for i=1:length(x)

    m=x(i);

    while(m>0)

        b=rem(m,10);

        if(b==k)

            c=c+1;

        end

        m=(m-b)/10;

    end

end

Sample Output:

JAVA CODE:

import java.util.Scanner;

class Duk

{

public static void main(String args[])

{

Scanner obj=new Scanner(System.in);

System.out.println("Enter the array length:");

int l=obj.nextInt();

int a[]=new int[l];

for(int i=0;i<l;i++)

{

System.out.println("Enter the "+i+"th element");

a[i]=obj.nextInt();

}

System.out.println("Enter the number you want to search:");

int k=obj.nextInt();

int m=0;

int b=0;

int c=0;

for(int i=0;i<l;i++)

{

m=a[i];

while(m>0)

{

b=m%10;

if(b==k)

{

c=c+1;

}

m=m/10;

}

}

System.out.println();

System.out.println(c);

}

}

Output:
