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.
参考代码如下:
public static void main(String[] args) {
// TODO Auto-generated method stub
int s;
String string1 = null;
String string2 = null;
Scanner scanner = new Scanner(System.in);
string1 = scanner.nextLine();
System.out.println("the first number:" + string1);
string2 = scanner.nextLine();
System.out.println("the second number:" + string2);
char a1[] = string1.toCharArray();
int a[] = new int[a1.length];
for (int i = 0; i < a1.length; i++) {
a[i] = Integer.valueOf(a1[i]).intValue() - 48;
}
char b1[] = string2.toCharArray();
int b[] = new int[b1.length];
for (int j = 0; j < b1.length; j++) {
b[j] = Integer.valueOf(b1[j]).intValue() - 48;
}
add(a, b);
}
public static void add(int c[], int d[]) {
int temp = 0;
int e[] = new int[50];
int c1 = c.length - 1, d1 = d.length - 1, e1 = e.length - 1;
while (c1 >= 0 && d1 >= 0) {
if (c[c1] + d[d1] > 9) {
e[e1] = c[c1] + d[d1] - 10 + temp;
temp = 1;
} else {
e[e1] = c[c1] + d[d1] + temp;
temp=0;
}
c1--;
d1--;
e1--;
}
while (c1 >= 0 || d1 >= 0) {
if (c1 >= 0) {
e[e1] = c[c1] + temp;
temp=0;
} else {
e[e1] = d[d1] + temp;
temp=0;
}
c1--;
d1--;
e1--;
}
System.out.println();
String sum=Arrays.toString(e);
System.out.println(sum);
}
