Question

如题所述

Answer 1

var sum = 0
for (var i = 0; i <= 100; i++) {
if (i % 3 == 0) {
sum += i
}
}
console.log(sum); //1683

Answer 2

var sum = 0;
for(i=1;i<=100 ;i++){
if(i%3 == 0){

sum = sum+i;//奇数

}
}
console.log("被3整除的数的和：" + sum);

Answer 3

int sum = 0;
int i;
for(i=1;i<=100;i++) {
if(i%3==0) {
sum+=i;
}
}System.out.println(sum);
