I was doing the bubble sorting project in digital systems,i had to compare 3 4bit numbers, but i released that after first competence of 2 numbers i get an output 1 bit number,so is there any way to get 4 bit output after comparisons. And also i wanted to know is there any way to display only decimal numbers on hex decimal display, i mean when the 4 bit number is more than 1010 the next number would be displayed on second display,i have seen some tutorials and most of them use hard scheme to display the numbers on 7 segment display

enter image description here
the comparing logic that i used
