click to show spoilers. Have you thought about this? Here are some good questions to ask before coding. Bonus points for you if you have already thought through this! If the integer's last digit is 0, what should the output be? ie, cases such as 10, 100. Did you notice that the ...
it returns the last digit as remainder.This remainder becomes the first digit ofreversenum, we are repeating this step again and again until the given number become zero and
if(ret != 0) {//must follow this pattern to checkif((Integer.MAX_VALUE - digit) / ret < 10)return0;if(neg_flag ==true) {if(-10 < (Integer.MIN_VALUE + digit) /ret)//- (ret * 10 + digit) < Integer.MIN_VALUE//if we convert the number to abs, we need to compare it i...
Output For each test case, you should output its reverse number, one case per line. Sample Input 3 12 -12 1200 Sample Output 21 -21 2100 注意:前导0的情况! 例: 输入: 3 -0012560020 00000 00205 输出为: -2006521 0 502 代码语言:javascript 代码运行次数: importjava.util.Scanner;publicclassM...
