I’m not a coder but I found the 7 mixed fruit solution pretty quickly using calc.exe and trial and error. Just a point of note: Looks to me like some of you were over-thinking the numbers – the dining party specified 15.05 of *appetisers*, so the Barbecue sandwich should not be included in the calculations (it’s under a different category on the menu)

I was playing around with the audio feature.

And instead of saying “I am” it says “I A-M”.

It made me giggle.

It is better to use ‘eq’ for that operation, not ‘==’.

Sorry, I meant:

function knapsack(num, list):
if list == {} or num < 0 then return false
elseif num == 0 then return {}
else
> a:=knapsack(num-list[0], list)
> if a then return {list[0]} + a
> else return knapsack(num, list[1:])
> endif
endif

Easy, simple… and for all the family! (stupid tags…)

Pseudocode:

function knapsack(num, list):
if list == {} or num a:=knapsack(num-list[0], list)
> if a then return {list[0]} + a
> else return knapsack(num, list[1:])
> endif
endif

Easy, simple… and for all the family!

use big numbers !!

$ perl -Mbignum -e ‘print 2.15*7, “\n”, 15.05, “\n”, (2.15*7 == 15.05) ? “true” : “false”, “\n”;’
15.05
15.05
true

I did mine in qBasic, and ran into the same problem. I have run into that problem over and over again when writing code, and I never learn from it.
