question have explained colleague valid , invalid possible combinations through image2.

in javascript simplest solution add if else statements , getting done.by doing gap between 1 explained solve business scenario in paper , code widens.

what best implementation of transferring matrix in paper code business in paper , code have close relation.

this question may sound vague @ least once faced issue things written solve problem in paper , way solved code makes no sense.

use binary arithmetic.

country values

india       0001 australia   0010 america     0100 england     1000 country 1111

climate value

hot         00001 dry         00010 rainy       00100 cold        01000 humid       10000 climate 11111

when choose second item, use and operation decide if value choosen, (all or same value).

example

var firstcountry = 0xf var secondcountry = 0x1 if ( (firstcountry & secondcountry) > 0) {     console.log("country choosen"); }

of course example 1 attribute. should update both attributes.
