freecodecamp 中级算法地址戳这里 Sum All Numbers in a Range 我们会传递给你一个包含两个数字的数组.返回这两个数字和它们之间所有数字的和. function sumAll(arr) { arr.sort(function(a,b){ return a-b; }); var a=arr[0]; var sum=arr[0]; while( a<arr[1] ){ a++; sum+=a; } return sum; } sumAll([1, 4]); Diff…
原题: Prime summations It is possible to write ten as the sum of primes in exactly five different ways: 7 + 35 + 55 + 3 + 23 + 3 + 2 + 22 + 2 + 2 + 2 + 2 What is the first value which can be written as the sum of primes in over five thousand different…
数组 ##数组的定义与赋值: 1. var num [3]int num = [3]int{1,2,3} 2. var num [3]int = [3]int {1,2,3} 3. num := [3]int{1,2,3} 4. num :=[...]int{1,2,3} 5. num :=[...]int{4:20,7:11} //定义下表为4的值是20,下表为7的值是11 切片 切片的定义与赋值: 1. primes := [8]int{1,2,3,4,5,6,7,8} //先定义赋值出一个…
