Note: The sum of three odd numbers is odd, so a+b+c=12 means at least one even
For a table with repeated solutions:▼
nmber (1 even, two odd or 3 even). Futher, 2a+b=12, a,b in (2,4,6) has one
solution: a=2,b=4
▲For a table with repeated solutions using nested loops:
<lang zkl>println("Police Fire Sanitation");▼
foreach p,f,s in ([2..7,2], [1..7], [1..7])
{ if((p!=s!=f) and p+f+s==12) println(p,"\t",f,"\t",s) }</lang>
▲println("Police Fire Sanitation");
