Shadow Hatake Posted March 26, 2006 Share Posted March 26, 2006 How would go about doing this? I'm putting in 7 variables, but how would I make a loop where each variable was only used once and made every possible comination?

You have seven variables and you want to do all combinations. The loop will be different if you consider (A and B) to be the same as (B and A) or not.i.e A*B == B*A but A-B != B-ATo create the loops your problem have to be more specified. All combinations can differ between two problems as you can see in the example abowe. [code]// A and B is the same as B and Afor($i=0;$i<7;$i++){ for($j=$i;$j<7;$j++) { math between var[$i] and var[$j] }}// A and B is not the same as B and Afor($i=0;$i<7;$i++){ for($j=0;$j<7;$j++) { math between var[$i] and var[$j] }}[/code] Quote Link to comment https://forums.phpfreaks.com/topic/5877-doing-a-cintunal-math-problem-until-solved/#findComment-20969 Share on other sites More sharing options...
