Output a five-digit palindrome
Emphasis
* " / " * to go to the front of the number "%" to go to the back of the number. then compare
for (int i = 10000; i <=99999; i++) {
int a=i/10000;取第一位
int b=i/1000%10;取第二位
int c=i/10%10;取第四位
int d=i%10;取第五位
if (a==d&&b==c) {
判断对应位置数字是否相同
System.out.println(i);
}
}
