qodirovshohijahon / array_arrayIsUniqueWithXOR.js

Last active January 9, 2020 16:32

In this example it is described how to specify unique numbers in array through XOR(bitwise).

	let result = 0;
	let arr = [1, 2, 5, 4, 6, 1, 2, 5, 4];
	for(let i = 0; i <= arr.length; i++){
	result = result ^ arr[i];
	}
	console.log(" this is an unique number " + result);

Last active January 11, 2020 13:55

In this example you can see one of the common way to reverse array elements using for loop.

	function reversedString (mystr) {
	let str = "";
	for(let i = mystr.length; i > 0; i--){
	str += i;
	}
	return str;
	}

qodirovshohijahon / array_reversing_v_0_2.js

Created January 11, 2020 13:54

In this example you can see one of the common way to reverse array elements using js build-in functions.

	function reversedStringWihtBuildinFunc(str) {
	return str.split("").reverse().join("");
	}

qodirovshohijahon / array_reversing_v_0_3.js

Created January 11, 2020 13:56

In this example you can see one of unique way to reverse array elements using recursive functions

	function reverseString (str) {
	if(str === "") return ""; else
	return reverseString(str.substr(1)) + str.charAt(0);
	}

qodirovshohijahon / swapping_v_0.1.js

Created January 13, 2020 13:30

In this example you will see swapping in js.

	function swappingUsingTwoVars(num1, num2) {
	num1 = num1 + num2;
	num2 = num1 - num2;
	num1 = num1 - num2;
	return ("First number " + num1 + "\nSecond number " + num2);
	}

	var subtractProductAndSum = function(n) {
	let num = n.toString().split("");
	let count = num.reduce((acc, sum)=>{
	acc += Number(sum);
	return acc;
	}, 0);

	var subtractProductAndSum = function(n) {
	let strNum = n.toString();
	let arr = strNum.split("");
	let mul = 1, count = 0;
	for (let i = 0; i < arr.length; i++) {
	mul *= arr[i];

Subtract the Product and Sum of Digits of an Integer

	var subtractProductAndSum = function(n) {
	if (n / 10 == 0)
	return 0;
	let mul = 1, sum = 0;
	while( n != 0) {
	mul *= n % 10;
	sum += n % 10;
	n = Math.trunc(n / 10);
	}
	return mul - sum;
