We have three $3-$bit up counter chips as shown in the picture with

Load and Enable features as well as two pushbuttons A and B$.$ When Load is

active, Q outputs are loaded with D inputs. Design a $3-$digit counter using the

counter chips and digital gates that :

$-$Counts $000-777$ if no push button is pressed

$-$Resets to $555$ if only push button A is pressed

$-$Resets to $333$ if only push button B is pressed

$-$Resets to $666$ if both push buttons are pressed

i need the entire solution with drawing and explanation not an explanation of how to draw please and thank you!
