Different methods to get unique array in JavaScript Method-1: Use theSetobject Within the JavaScript environment, there is a native and built-in object calledSet, which allows us to store unique values of any data type. The collections of values within aSetobject may only occur once, and the...
Array.prototype.unique=function() {// 原数组先排序this.sort();// 构建一个新数组存放结果varnewArray = [];for(vari =1; i <this.length; i++) {// 检查原数组中的第i个元素与结果中的最后一个元素是否相同// 因为排序了,所以重复元素会在相邻位置if(this[i] !== newArray[newArray.length-1...

unique pointer是个non-copiable object,请参考上面的By value说明,unique pointer不能直接copy,必须std::move()下才可以,即unique pointer的copy内部就是右值引用。 所以,用copy by value和右值引用,本质上,没有什么区分,用哪个都可以。 但理论上,对于unique pointer,右值引用还是和copy by value有稍微不同,大家...

和std::auto_ptr一样,std::unique_ptr也是一种智能指针,它也是通过指针的方式来管理对象资源,并且在 unique_ptr 的生命期结束后释放该资源。 unique_ptr 持有对对象的独有权 —— 两个 unique_ptr 不能指向一个对象,...
