ProblemWe are required to write a JavaScript function that takes in a time string in “HH:MM:SS” format.But there was a problem in addition, so many of the time strings are broken which means the MM part may exceed 60, and SS part may as well exceed 60.Our function should make ... Read More

ProblemWe are required to write a JavaScript function that takes in two IPv4 addresses, and returns the number of addresses between them (including the first one, excluding the last one).This can be done by converting them to decimal and finding their absolute difference.ExampleFollowing is the code − Live Democonst ip1 = ...

ProblemWe are required to write a JavaScript function that takes in a number n. Our function should convert the number to binary or hex based on −If a number is even, convert it to binary.If a number is odd, convert it to hex.ExampleFollowing is the code − Live Democonst num = ... Read More

K-Prime NumbersA natural number is called k-prime if it has exactly k prime factors, counted with multiplicity.Which means even though the only prime factor of 4 is 2 it will be a 2-prime number because −4 = 2 * 2 and both 2s will be counted separately taking the count ... Read More

ProblemWe are required to write a JavaScript function that takes in an array of numbers. For each number in the array, we need to create an object. The object key will be the number, as a string. And the value will be the corresponding character code, as a string.We should ... Read More

ProblemWe are required to write a JavaScript function that takes in an array of numbers. Our function is supposed to return the average of the given array rounded down to its nearest integer.ExampleFollowing is the code − Live Democonst arr = [45, 23, 67, 68, 12, 56, 99]; const roundedMean = ...
