Write a pseudo code + Draw Flowchart that find the biggest of three (3) Numbers

Sure, here is a simple pseudocode for finding the biggest of three numbers:

1. Start
2. Input number1, number2, number3
3. If number1 > number2 and number1 > number3 Then
4.    Print number1 is the biggest
5. Else If number2 > number1 and number2 > number3 Then
6.    Print number2 is the biggest
7. Else
8.    Print number3 is the biggest
9. End If
10. Stop

And here is a simple flowchart:

  Start
    |
    V
Input number1, number2, number3
    |
    V
number1 > number2 and number1 > number3?
    |                    |
   Yes                  No
    |                    |
    V                    V
Print number1 is     number2 > number1 and number2 > number3?
the biggest              |                    |
                          Yes                  No
                          |                    |
                          V                    V
                      Print number2 is     Print number3 is
                      the biggest          the biggest
                          |                    |
                          V                    V
                         End                 End
