大整数相关的几道题

1、大整数相加

void plus(String input1, String input2) {

char[] input11 = input1.toCharArray();

char[] input21 = input2.toCharArray();

   4:  

int len1 = input11.length, len2 = input21.length;

   6:  

int len = len1 > len2 ? len1 : len2;

// 结果数组

   9:  

int[len];

int[len];

  12:  

// 数据反转 因为下标的因素

int i = 0; i < len; i++) {

// input1长,input2补位0

if (len == len1) {

'0';

if (i < len2) {

'0';

else

  21:                     number2[i] = 0;

else {

'0';

if (i < len1) {

'0';

else

  27:                     number1[i] = 0;

  28:             }

  29:         }

  30:  

//print(number1);

//print(number2);

  33:  

int count = 0;

  35:  

int i = 0; i < len; i++) {

  37:             result[i] += number1[i] + number2[i];

if (result[i] > 10) {

// 进位

  40:                 result[i] = result[i] % 10;

  41:             }

  42:  

  43:         }

  44:  

if (result[len] != 0)

  46:             count = len;

else

  48:             count = len - 1;

  49:  

int i = count; i >= 0; i--) {

  51:             System.out.print(result[i]);

  52:         }

  53:         System.out.println();

  54:     }

  55:  

int[] number) {

int i = number.length - 1; i >= 0; i--) {

  58:             System.out.print(number[i]);

  59:         }

  60:         System.out.println();

  61:     }

  62:  

void main(String[] args) {

// TODO Auto-generated method stub

  65:  

);

  75:  

  76:         plus(input11, input12);

  77:         plus(input21, input22);

  78:         plus(input31, input32);

  79:     }
