Binary Coded Decimal (BCD)

Binary-Coded Decimal is a method of encoding decimal using binary. One application of BCD is for a block. Assume that we have a clock that represents time using BCD to encode HOURS (H), MINUTES (M), and SECONDS (S). Write the time indicated by the clock as well as if the time is a valid time using a 24 hour clock (sometimes referred to as “military time”).
