7:06 AMFriday, November 7, 2014
Problem: Algorithm to find maximum of two unequal numbers and use the same to find maximum of four unequal numbers.

Input: For sub-algorithm 2 numbers and for main algorithm 4 numbers.

Output : Returns the maximum of 4 numbers

MAX_OF_2(NUM1, NUM2)      [Sub-algorithm]
[NUM1 and NUM2 are two numbers]
If(NUM1>NUM2) Then:
Returns NUM1
Else:
Return NUM2
[End of If]
Exit.
MAX_OF_4(NUM1, NUM2, NUM3, NUM4)
[NUM1, NUM2, NUM3, and NUM4 are numbers]
TEMP1 <-- MAX_OF_2(NUM1, NUM2)
TEMP2 <-- MAX_OF_2(NUM3, NUM4)
MAX   <-- MAX_OF_2(TEMP1, TEMP2)
Return MAX
Exit.
