JavaScript 算法之 判断是否为质数 prime number 素数 质数：只能被1和自己整除且大于1的数。合数：数大于1且因数多余2个（大于1的数质数的补集）。function isPrimeNumber1(n){if(n < 2) return false;if(n === 2) return true; // 最小的质数for(let i = 2; i < n; i++){if(n % i ...

A number is prime if it has only two distinct divisors: 1 and itself. For example, 3 is a prime number because it has only two distinct divisors: 1 and 3. Return "Prime" if num is prime; otherwise, return "Not Prime". 1 2 3 function checkPrime(num) { } Check Code Share ...
substring(pos+1); // Note that all the variables we define are strings. // Scripts can convert them to other types if necessary. // We could also pass a java.lang.Number, a java.lang.Boolean // or any Java object or null. bindings.put(name, value); } else { if (filename != ...
freeCodeCamp (JavaScript中级算法题)学习 1、范围内的数字求和 我们会传入一个由两个数字组成的数组。 给出一个含有两个数字的数组,我们需要写一个函数,让它返回这两个数字间所有数字(包含这两个数字)的总和。 最低的数字并不总是第一位。 例如,sumAll([4,1])应返回10,因为从 1 到 4(包含 1、4)的...

You may play with data-structures and algorithms in./src/playground/playground.jsfile and write tests for it in./src/playground/__test__/playground.test.js. Then just, simply run the following command to test if your playground code works as expected: ...
