**Steps we will follow:**

a) Lets we have an array of size 25.

b) First start with 2, remove all numbers which are divisible by 2.

c) Find the next number, which is 3. Remove all numbers which are divisible by 3.

d) Next survivor is 5 and we repeat the same procedure.

e) For the given limit 25, we don't need to find anymore survivor after 5, as 5 X 5 = 25. In other words, we only process up to the square root of the limit.

f) All survivor numbers in the array are Prime. We save those numbers in a separate array.
