Greatest of Three

Summary

The problem is to find the greatest number among three given integers. This is a classic example of a simple comparison problem that can be solved using conditional statements.

Detailed Explanation

To solve this problem, we need to write a program that takes three integers as input and returns the largest one. We can use if-else statements or ternary operators to compare the numbers and find the greatest one.

Here's a step-by-step breakdown of the solution:

1. Read three integers from the user (or take them as input in your program).
2. Compare the first two numbers using an if statement.
   • If the first number is greater, set it as the maximum value.
   • Else, set the second number as the maximum value.
3. Now, compare the third number with the current maximum value.
   • If the third number is greater than the maximum value, update the maximum value to be the third number.

Here's a simple diagram illustrating this process:

    +-------+
    |  Num1  |
    +-------+
           |
           | (Compare Num1 and Num2)
           v
    +-------+       +-------+
    |  Max   |       |  Num2  |
    +-------+       +-------+
           |             |
           | (Compare Max and Num3)
           v
    +-------+       +-------+
    |  Max   |       |  Num3  |
    +-------+       +-------+

The time complexity of this algorithm is O(1), as we only perform a constant number of operations. The space complexity is also O(1), as we don't use any extra space that scales with the input size.
