Given a non-negative number represented as an array of digits, plus one to the number.
The digits are stored such that the most significant digit is at the head of the list.
1 public class Solution { 2 public int[] plusOne(int[] digits) { 3 digits[digits.length - 1] += 1; 4 for(int i = digits.length - 1; i >=0 ; i--){ 5 if((digits[i] / 10) == 1 && i != 0){//有进位 6 digits[i] = digits[i] % 10; 7 digits[i - 1] += 1;//向高位进1 8 } 9 } 10 if(digits[0] / 10 == 0) 11 return digits; 12 else{ 13 int result[] = new int[digits.length + 1]; 14 System.arraycopy(digits, 0, result, 1, digits.length); 15 result[0] = 1; 16 result[1] %= 10; 17 return result; 18 } 19 } 20 }
