在JavaScript中,算法只是一个函数,它将某个确定的数据结构输入转换为某个确定的数据结构输出。函数内部的逻辑决定了怎么转换。首先,输入和输出应该清楚地提前定义。这需要我们充分理解手上的问题,因为对问题的全面分析可以很自然地提出解决方案,而不需要编写任何代码。 一旦完全理解了问题,就可以开始对解决方案进行思考,...
import java.util.Scanner; public class Exercise16 { public static void main(String[] args) { for (int i = 2; i < 100; i++) { if (is_Prime(i) && is_Prime(i + 2)) { System.out.printf("(%d, %d)\n", i, i + 2); } } } public static boolean is_Prime(long n) { if...

此Array.findIndex()方法可用於查找數組中素數的元素的索引(如果沒有素數則返回-1)。 讓我們看一下JavaScript程序: // function isPrime is used to find which// number is prime or not prime.functionisPrime(n){if(n ===1) {returnfalse; }elseif(n ===2) {returntrue; }else{for(varx =2; x...

log(evenPrime); // 输出: undefined 在这个例子中,由于primes数组中没有偶数质数,find()方法返回undefined。 综上所述,Array.find()方法在JavaScript中是一个强大且实用的数组查找工具,它根据提供的条件查找并返回数组中的第一个匹配元素,或者在没有找到匹配元素时返回undefined。
