QUESTION
It is different from the coin-changing problem link.
Given a dict x=[a:1,b:2,c:1,d:3,e:2]
, I need to calculate all possible combinations of the keys such that the sum of the values associated with those keys just exceeds or equals a given value, say 5. Just exceeding 5 means that if the selected elements are lower than 5, we can add one more element even if it exceeds 5 but once we exceed or equal 5, no more elements can be added.
There are two issues that are complicating my approach -
- Note that some of the values are repeated-e.g. 1 and 2 each occurs twice and they need to be considered separately.
- Ordering matters in this case.
Ordering matters too so [b,c,d], [b,d,c], [c,b,d], [c,d,b], [d,b,c], [d,c,b]
are all included separately. Ideally ordering matters only when we are exceeding 5 and as long as the sum is exactly 5, ordering doesn't matter.
So some of the solution to the above question are [a,b,c,d]
with sum 7, [a,b,c,e]
with sum 6, [b,c,d]
with sum 6, [d,e]
with sum 5 etc.
How do I approach the problem. I was thinking of using the output from coin changing and then adding one element to each of the resulting lists, but that will not cover all the cases.
EDIT 1: A better way of framing the question might be to find all combinations such that the sum (i) equals 5 or (ii) just exceeds 5 as the sum until the second last element was less than 5 and therefore adding the last element made it greater than 5. Once we have 5 or >5, no additional elements will be added.
EDIT 2: Clarifying the ordering issue. To give a bit of context, the keys are devices and the values are the resources it needs. And the total resources available is 5. And the devices are allocated resources as per their keys i.e. the first key-value pair will be serviced first (sorted as per the key alphabetically). For b
, it needs 2 but say only 1 resource is available - it will be assigned 1 and the remaining 1 will be assigned in the next run (spillover). So when the sum is exactly 5, the order doesn't matter as each gets whatever it wanted and there is no spillover to the next slot. E.g. ed
and de
means both get what they wanted so they should both be included.
But for lists that exceed 5 just due to the addition of the last element, ordering matters as spillover will happen only for the last element. E.g. dce
means d and c get 3 and 1 respectively, and e gets only 1 (with 1 spilling into next run). Similarly ced
means c and d get 1 and 3 respectively, with spillover happening for d as it only gets assigned 1.

QUESTION
So I have two arrays of materials and bits. I create a constant selectedbits and filter it comparing if the properties of material are the same as well as if the property cel of bits is longer than a user input value. This should then return the bits that are available as the selectedBits. That part works. I can see when inspecting that the correct bits are being populated. But can't seem to get the selectedBit.name to print/populate the select dropdown.
The result I get is filtered as the correct number of dropdown items are showing but the values are "undefined".
< option value="undefined">undefined (modified the html so it would display here).

I have to make a Tictactoe for a project, and while i do know that the code is not good, i can´t see what the error is, the value is assigned to the dict, if i print the key for the last play its correctly show me if is an X or a O, but the value is not represented in the last print of the board.
...ANSWER
Answered 2020-Oct-22 at 14:43You are assigning the new X
or O
to tablero['algo']
. If the game doesn't end here, you assign the contents of tablero
to ari
, arc
, etc., but only at the start of the next loop.
So if the game does end after that move, you print the old ari
, arc
, etc. which have not yet been updated to reflect the latest move.
Of course, there are many other things you should fix (lots of repetition that can be avoided), but the game does work correctly.
Some suggestions:
I would use a simple list to handle the board. tablero = [" "] * 9
creates a list of nine space characters. This allows for a lot of simplications down the line. For example, to print the board, you can simply do

...ANSWER
Answered 2020-Sep-01 at 07:54You shouldn't update start_char
in the inner loop, just at the beginning of each line. There's also no need to make this a character, if you're just going to convert it back to a number with ord()
. Just put the number there.
Using zero-based loops means you don't have to subtract 1.
QUESTION
I have an Access database that I use to track personnel going on trips. When I add someone to a trip, it copies over some information items from the master personnel table into another table that ties that person to the trip and then displays readiness things that I need to track. I'm in the process of updating how the front end talks to the back end in preparation for migrating this over to a proper SQL server rather than just a backend file on a share drive, and was wondering if there was a better way to code this.
Here's the original code:

QUESTION
I have some code that creates instances from a list of classes that is passed to it. This cannot change as the list of classes passed to it has been designed to be dynamic and chosen at runtime through configuration files). Initialising those classes must be done by the code under test as it depends on factors only the code under test knows how to control (i.e. it will set specific initialisation args). I've tested the code quite extensively through running it and manually trawling through reams of output. Obviously I'm at the point where I need to add some proper unittests as I've proven my concept to myself. The following example demonstrates what I am trying to test:
