Diagnosis 2.2. A prime number is a number that has exactly two factors, 1 and the number itself. However, it's still not big enough to store the value of bigger numbers (say 100). So, inside that loop print(2), and divide the number by 2 in each iteration. You are given a positive integer 'N'. The 'if-else' statement executes different code based on whether the condition is true or false. Classroom. To solve this program programmatically, we can use a loop that will check all numbers from 1 to that number. A HashMap has nodes that contain the key value pair much like a node in a Map. The for loop is iterated until i <= number is false. Two ways are shown to Print Multiplication Table for any Number: Method 1: Generating Multiplication Table using for loop upto 10, Method 2:- Generating Multiplication Table using while loop upto any given range, Time complexity: O(n) where n is given input range.
