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)....
Let, variableacontains first value, variablebcontains second value. Step 1: a = a + b Step 2: a = a - b Step 3: b = a - b Scala code to swap two number without using third variable objectmyObject{defmain(args:Array[String]):Unit={vara=10varb=20println("Values before swapping:...
Write a JavaScript program to swap variables from one to another. Swapping two variables refers to mutually exchanging the values of the variables. Generally, this is done with the data in memory. The simplest method to swap two variables is to use a third temporary variable : define swap(x,...
Explanation: In the above program, we imported a packageSwiftto use theprint()function using the below statement, import Swift; Here, we created two integer variablesnum1andnum2that are initialized with 5, 8 respectively. Then we interchanged the values of variables using the bitwise XOR (^)...
Write a JavaScript program to swap two bits (from the right side, the rightmost position is 0) in the binary representation of an integer at the given position. Test Data: (245) -> 249 Explanation: 245 -> 11110101 Swap the 1st and 4th bits from the side of the said binary number. ...
This function swaps two items in an array based on their indices. JavaScript: let swapItems = (arr, i, j) => ([arr[i], arr[j]] = [arr[j], arr[i]], arr); // Example console.log(swapItems(['a', 'b', 'c', 'd', 'e'], 1, 3)); // ['a', 'd', 'c', 'b'...
XOR the two numbers again and store the result in the first number (x = 2 ^ 5 so x = 7)Below is the program to swap two numbers using bitwise operator.#include<stdio.h> #include<conio.h> void main() { int x = 6, y = 4; x = x^y; y = x^y; x = x^y; printf("x ...
N: number of indexed elements. xp: input Float64Array pointer (i.e., byte offset). sx: index increment for x. yp: input Float64Array pointer (i.e., byte offset). sy: index increment for y. dswap.Module.prototype.ndarray( N, xp, sx, ox, yp, sy, oy ) Interchanges two double...

Bitwise XOR (^):The bitwise XOR operator (^) returns a 1 in each bit position for which the corresponding bits of either but not both operands are 1s. Here, we will create two variables then we will swap the value of variables using the bitwise XOR (^) operator and print the updated...
