Psuedocode, finding highest value in an array

Hi, I'm a total novice at computing and have been asked to find the highest value in a 2D array.

This is what I have to fill in....

Code:

---

;--------------------------------------------------------------------
; Given a 2-D array of sales. 
; Print out each individual item with a total of the sales for that
; item.
; Print out the name of the item with the
; highest single monthly sale, the month it sold, and the amount. 
;--------------------------------------------------------------------

define MAXPRODUCTS = 5                        ; Maximum number of products
string Product[MAXPRODUCTS] = "WKD", "ICE", "Red Bull", "Rentless", "Monster"
integer Sales[MAXPRODUCTS, 2] = 2000, 1650, 1500, 2050, 1800, 1700, 2200, 2400, 1750, 1550

begin
        ; Print out all items and total for each
        PrintAll ()                                        ; Call procedure to print all       
       
        ; Find the item with the highest single monthly sale
        FindHighest ()                                ; Call procedure to find best seller
end

;--------------------------------------------------------------------
; Procedure to print out all the items and the sales
;--------------------------------------------------------------------
procedure PrintAll ()


end procedure


;--------------------------------------------------------------------
; Procedure to Find Highest selling product
;--------------------------------------------------------------------
procedure FindHighest ()


end procedure

Thanks for any help

Finding extreme values is standard procedure.

Introduce a variable called maxValue or something. Assign the first value of the array to maxValue. Then loop through all values in the array once and for each value check whether it's higher than maxValue. If it is, assigned it to maxValue. Afterwards maxValue will hold the highest value of the array.
