PART 1
PART 2
Assume we have already defined a variable of type int called num with the following line of code: int num = ???; // 'num' can have any int value TASK: Print a centered triangle with num asterisks (*) on the bottom row, num - 2 asterisks on the next bottom row, ., and 1 asterisk on the top row, where the triangle is surrounded by hyphens (). You can assume that num is odd and is at least 3. EXAMPLE: If num is 5, the resulting triangle would be the following: --*-- - ***** Sample Input: Sample Output: --*-- -***- ***** Assume we have already defined a variable of type int called num with the following line of code: int num = ???; // 'num' can have any int value TASK: Print the prime numbers that are less than or equal to num (one per line). You may assume that num is greater than 1. HINT: Recall that a number is considered "prime" if it is only divisible by 1 and itself. HINT: 1 is not a prime number. HINT: You can use Math.sgrt(x) to take the square root of a variable x. No need to import anything: we've done that for you behind-the-scenes. Sample Input: 10 Sample OutputStep by Step Solution
