After the placement that constitutes everything, the placement that does not meet the conditions is removed. 2. Program source code: main(){inti,j,k;printf(\n);for(i=1;ilt;5;i )/
The following is a triple loop
/for(j=1;jlt;5;j )for(k=1;klt;5;k ){if(i!=ki!=jj!=k)/
Make sure that i, j, and k are different from each other
/printf(
