Mark multiples of each number as non-prime
Remaining unmarked numbers are prime
ArrayList is better for random access and LinkedList is better for frequent insertions and deletions.
ArrayList uses dynamic array to store elements, allowing fast random access but slower insertions and deletions.
LinkedList uses doubly linked list to store elements, allowing fast insertions and deletions but slower random access.
Example: Use ArrayList when you need to frequently access elements by index. Use LinkedList...
List is an ordered collection, Set is a collection with no duplicates, Map is a key-value pair collection.
List maintains insertion order, Set does not allow duplicates, Map stores key-value pairs
List example: ArrayList, Set example: HashSet, Map example: HashMap
Calculate average salary of employees
Sum up all the salaries of employees
Divide the total sum by the number of employees to get the average
Example: salaries = [50000, 60000, 70000], average = (50000 + 60000 + 70000) / 3
Given two arrays [1, 1, 2, 3, 1] and [2, 1, 1, 3, 1], write the code to check for their equality, where equality means that both arrays contain the same elements. Approach 1 involves sorting the arrays and then using a for loop to check for equality; however, sorting has a higher time complexity. The interviewer prefers a solution with O(n) time complexity. Approach 2 suggests using a HashMap to count the occurrences of each element, allowing us to achieve this in O(n) time complexity.
