Print numbers from 1 to 5.

To print numbers from 1 to 5, you can use a simple for-loop that iterates over the range of numbers. In Python, the range function generates a sequence of integers, and you can start at 1 and end at 5 inclusive by using range(1, 6). Inside the loop, you print each number. The algorithm runs in O(n) time, where n is the count of numbers to print (in this case, 5). It also uses O(1) additional space. Example code:

for i in range(1, 6):

print(i)

This will output:

1

2

3

4

5

The same logic applies to other languages: use a for-loop with an index starting at 1 and incrementing until it reaches 5. The key concepts are understanding loop boundaries and the inclusive/exclusive nature of the end value in the chosen language.
