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) 
		return false
	for (i=2; i<n; i++){ 
		if (n%i == 0)
			return false
	}
	return true

Algorithm : 
Input: num
(1) Initialize rev_num = 0
(2) Loop while num > 0
(a) Multiply rev_num by 10 and add remainder of num 
divide by 10 to rev_num
rev_num = rev_num*10 + num%10;
(b) Divide num by 10
(3) Return rev_num

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])
}

Make group of 5 horses and run 5 races. Suppose five groups are a,b,c,d,e and next alphabet is its individual rank in this group(of 5 horses).for eg. d3 means horse in group d and has rank 3rd in his group. [ 5 RACES DONE ] 
a1 b1 c1 d1 e1 
a2 b2 c2 d2 e2 
a3 b3 c3 d3 e3 
a4 b4 c4 d4 e4 
a5 b5 c5 d5 e5 

Now make a race of (a1,b1,c1,d1,e1).[RACE 6 DONE] suppose result is a1>b1>c1>d1>e1 
which implies a1 must be FIRST. 
b1 and c1 MAY BE(but not must be) 2nd and 3rd. 
FOR II position, horse will be either b1 or a2 
(we have to find top 3 horse therefore we choose horses b1,b2,a2,a3,c1 do racing among them [RACE 7 DONE]. 
The only possibilities are : 
c1 may be third 
b1 may be second or third 
b2 may be third 
a2 may be second or third 
a3 may be third 
The final result will give ANSWER. suppose result is a2>a3>b1>c1>b2 
then answer is a1,a2,a3,b1,c1. 
HENCE ANSWER is 7 RACES.

1. Fill 3 liter jug from tap.
2. Empty it into 5 liter jug. 
3. Again fill 3 liter jug from tap 
4. Pour 2 liter (after that 5 liter jug will be full) from 3 liter jug into 5 liter leaving 1 liter in 3 liter jug.
5. Pour away the water of 5 liter jug.
6. Empty 1 liter water from 3 liter jug into 5 liter jug.
7 Fill 3 liter jug from tap and empty it into 5 liter jug .
8. 5 liter jug has 4 liters of water
