1016 part a+b

Positive integer  A  Of “DA​（ by 1 An integer ） part ” Defined by  A  All in  DA​  A new integer composed of  PA​. for example ： Given  A=3862767,DA​=6, be  A  Of “6 part ”PA​  yes 66, because  A  There is 2 individual 6.

Now given  A、DA​、B、DB​, Please write a program to calculate  PA​+PB​.

Input format ：

The input is given in turn on a line  A、DA​、B、DB​, Space between , among  0<A,B<109.

Output format ：

Output in one line  PA​+PB​  Value .

sample input 1：

3862767 6 13530293 3

sample output 1：

399

sample input 2：

3862767 1 13530293 8

sample output 2：

0

The code is as follows ：

 

#include<stdio.h>
int main()
{
	int a, a1, b, b1,i,k1=0,k2=0,j;
	scanf("%d %d %d %d", &a, &a1, &b, &b1);
	int ma = 0, mb = 0;// Sum up 
	for (i = 0; a > 0; a /= 10)
		if (a % 10 == a1)
			k1++;
	for (i = 0; b > 0; b /= 10)
		if (b % 10 == b1)
			k2++;
	for (j = 0; j < k1; j++)
		ma = ma * 10 + a1;
	for (j = 0; j < k2; j++)
		mb = mb * 10 + b1;
	printf("%d", ma + mb);
	return 0;
