We are required to write a JavaScript function that takes in an array of numbers as the first and the only argument. The function should first pick the smallest number from the array and then calculate the sum of all the digits of the number.If the digit sum of that ... Read More

In the number system, the Greatest Common Divisor (GCD) of two numbers is that greatest number which divides both the numbers. Similarly, if we apply this concept to strings, the gcd of two strings is the greatest substring (greatest in length) that is present in both the strings.For example −If ... Read More

We are required to write a JavaScript function that takes in an array of string words as the first argument. The second argument to the function will be a string containing all 26 English lowercase alphabets but in some random scrambled order.The task of our function is to check whether ... Read More

We are required to write a JavaScript function that takes in a number as the first and the only argument. The function should then square every digit of the number, append them and yield the new number.For example −If the input number is −const num = 12349;Then the output should ... Read More

Suppose we have a keyword, which instead of the traditional qwerty type key mapping, maps keys simply according to the english alphabetic order i.e., abcde...Before we dive into the problem, we have to make the following two assumptions −Currently our fingertip is placed at index 0, i.e., the key 'aThe ...
