plzzzzzz solve it quickly step by step

You have three common cathode 7-segment displays, 3 WWN trarsitus, tree estis ats PIC 16887 to display what is showing on the three 7 -segnent dsplas (ORd) a. Draw the circuit diagram (Use Port 8 to send the data to be ospared ass se got 0 s soent the 7-segment displays) b. Write a C program to display what is showing on the tree 7-segnert dispias (sthow your calculatinn)
