id.

i) Convert N to binary.

ii) Convert N to hexadecimal

Answer 1

Start
   Declare integer varaible N
   Declare array integer binary[40]   
   Declare integer varaible index = 0    
   Read N
   while decimal > 0 do   
       Set binary[index] = decimal mod 2
       Set index=index+1
       Set decimal = decimal/2
   End while
   for i = index-1 to  0 Step -1
       print binary[i]
   end for
   Declare integer variable rem       
   Declare string variable  result=""
   Declare char array hex[]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'}
   While num>0 do
       rem=num mod 16
       result=hex[rem]+result
       num=num/16
   End while
   print result
