How do you swap 2 elements in an array, in JavaScript?Suppose we have an array a which contains 5 letters.const a = ['a', 'b', 'c', 'e', 'd']We want to swap element at index 4 (‘d’ in this case) with the element at index 3 (‘e’ in this case)....
2) Swapping two numbers without using third variable We can also swap two numbers without using the third variable. This method saves computation space hence is more effective. Let, variableacontains first value, variablebcontains second value. Step 1: a = a + b Step 2: a = a - b Step...

In JavaScript, the bitwise XOR operatorn1 ^ n2performs the XOR operation on each bit ofn1andn2numbers. For example, here's how5 ^ 7evaluates to2: 1 0 1 (5 in binary) 1 1 1 (7 in binary) --- 0 1 0 (5 ^ 7 = 2 in binary) Bitwise...
JavaScriptswap用法jsswap函数 最近想自学javascript,今天一边查书一边学着写一些简单的函数之类的东西,由于之前学过C语言,自然而然的想着js中是否也有像C里面的指针,引用形参之类的东西,于是想写个交换两个变量的值的函数(swap),然而似乎不太简单。 JavaScript swap用法 ...
晚上看到一篇非常有意思的文章《Swapping of two numbers》,讲的是如何用Java语言实现swap方法。看到作者的代码,实在逗坏了,而且这篇文章在Google搜索如何实现Javaswap中排名非常靠前,如果感兴趣可以看一下文章以及评论。 ##BadSwap实际上类似作者的交换代码,在Java中是无效的。原因是Java中参数传 ...
