Ans. 
The naïve approach for this question is to run a loop from the start to the end number. And for each number, check if it is prime or not. If the number is prime, we print it otherwise skip it.
One optimization to this approach would be to skip all even numbers (except 2 if present in interval) since even numbers are not prime.
Function to check if a number is prime or not :
isPrime(n):
	if (n <= 1)

Ans. 
Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order.
Pseudocode:
bubbleSort(arr[], n) 
{ 
	for (i = 0 to i < n-1) do :
	// Last i elements are already in place 
		for (j = 0 to j < n-i-1) do : 
			if (arr[j] is greater than arr[j+1]) 
				swap(arr[j], arr[j+1])
}
