给出两个正数n和m。您只需要简单地找到两个数字的加法，但在给定条件下，该加法中没有任何进位系统。在更高的MSB上不添加进位。
例子 ：
Input : m = 456, n = 854
Output : 200
Input : m = 456, n = 4
Output : 450算法 ：
Input n, m while(n||m)
{
// Add each bits
bit_sum = (n%10) + (m%10);
// Neglect carry
bit_sum %= 10;
// Update result
// multiplier to maintain place value
res = (bit_sum * multiplier) + res;
n /= 10;
m /= 10;
// Update multiplier
multiplier *=10;
} print res方法 ：
为了解决这个问题，我们将需要对数字进行逐位加法，即从最右边的位(LSB)开始加两个数，并从两个相同位置的nuber中加整数。同样，我们将忽略每个位置的进位，以使进位不会影响更高的位。
开始将两个数字逐位相加，然后对每个位取整数和，然后通过对bit_sum取模乘以10来忽略它们的进位，通过将bit_sum与指定位值的乘数相乘，再将bit_sum加到res上。 (乘数在每次迭代中增加10倍。)
下面是上述方法的实现：
C++
// CPP program for special
// addition of two number
#include
using namespace std;
int xSum(int n, int m)
{
// variable to store result
int res = 0;
// variable to maintain
// place value
int multiplier = 1;
// variable to maintain
// each digit sum
int bit_sum;
// Add numbers till each
// number become zero
while (n || m) {
// Add each bits
bit_sum = (n % 10) + (m % 10);
// Neglect carry
bit_sum %= 10;
// Update result
res = (bit_sum * multiplier) + res;
n /= 10;
m /= 10;
// Update multiplier
multiplier *= 10;
}
return res;
}
// Driver program
int main()
{
int n = 8458;
int m = 8732;
cout << xSum(n, m);
return 0;
} Java

bit_sum %= 10;
// Update result
res = (bit_sum * multiplier) + res;
n /= 10;
m /= 10;

}
return res;
}

{
int n = 8458;

System.out.println(xSum(n, m));
}
}
