Problem Description

I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B.

Input

The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines follow, each line consists of two positive integers, A and B. Notice that the integers are very large, that means you should not process them by using 32-bit integer. You may assume the length of each integer will not exceed 1000.

Output

For each test case, you should output two lines. The first line is "Case #:", # means the number of the test case. The second line is the an equation "A + B = Sum", Sum means the result of A + B. Note there are some spaces int the equation. Output a blank line between two test cases.

Sample Input

1 2

112233445566778899 998877665544332211

Sample Output

Case 1:

1 + 2 = 3

Case 2:

112233445566778899 + 998877665544332211 = 1111111111111111110

#include<stdio.h>

#include<string.h>

#define MAX 1100

char str1[MAX],str2[MAX];

int a[MAX],b[MAX];

int main()

{

	int n,m,j,i,s,t,l1,l2,k,ok;

	scanf("%d",&t);

	k=1;

	while(t--)

	{

		memset(a,0,sizeof(a));

		memset(b,0,sizeof(b));

		scanf("%s%s",str1,str2);

		l1=strlen(str1);

		l2=strlen(str2);

		for(i=l1-1,j=0;i>=0;i--)

		{

			a[j]=str1[i]-'0';

			j++;

		}

		for(i=l2-1,j=0;i>=0;i--)

		{

			b[j]=str2[i]-'0';

			j++;

		}

		n=0;

		if(l1<l2)

		{

			n=l1;

			l1=l2;

			l2=n;

		}

	    for(i=0;i<l1;i++)

	    {

	    	a[i]=a[i]+b[i];

	    	if(a[i]>=10)

	    	{

	    		a[i]-=10;

	    		a[i+1]++;

	    	}

	    }

	    ok=0;

	    if(a[l1]>0)

	    {

	    	ok=1;

	    }

	    printf("Case %d:\n",k++);

	    printf("%s + %s = ",str1,str2);

	    if(!ok)

	    for(i=l1-1;i>=0;i--)

	    printf("%d",a[i]);

	    else

	    for(i=l1;i>=0;i--)

	    printf("%d",a[i]);

	    printf("\n");

	    if(t)

	    printf("\n");

	}

	return 0;

}
