We are given an array of distinct integers, let’s say arr, and another array of integer arrays, let say sourceArr.In the sourceArr array, the integers are distinct. We should write a function that forms arr by concatenating the arrays in sourceArr in any order.However, we cannot reorder the integers inside ... Read More

We are required to write a JavaScript function that can compare two strings and return the percentage likeliness of how much they are alike. The percentage will be nothing but a measure of many characters the two strings have in common.If they are completely similar the output should be 100, ... Read More

We are required to write a JavaScript function that takes in an array of numbers. The function should sort the array of numbers on the following criteria −---If the array contains any zeros, they should all appear in the beginning.---All the remaining numbers should be placed in a decreasing order.For ...

We are required to write a JavaScript function that takes in a number. The function should first calculate the factorial of that number and then it should return the sum of the digits of the calculated factorial.For example −For the number 6, the factorial will be 720, so the output ... Read More

We are required to write a JavaScript function that takes in a number, say n. The function should count the letters in the number names from 1 to n.For example − If n = 5;Then the numbers are one, two, three, four, five.And the total number of letters are 19, ... Read More

Suppose, we have a reference array of phrases like this −const reference = ["your", "majesty", "they", "are", "ready"];And we are required to join some of the elements of above array based on another array so if another array is this −const another = ["your", "they are"];The result would be like ...
