how could the seven-segment display driver be designed using a 4-to-16 decoder and logic gates rather than multiplexers?
A digital combinational logic circuit known as a digital or binary decoder can change one kind of digital code into another.
A particular decoder called a BCD to 7-segment display decoder may change binary coded decimals into a format that can be easily viewed on a 7-segment display. Four binary weighted address inputs (A0 to A3) are decoded to produce sixteen mutually exclusive outputs (Y0 to Y15). The device has two inputs that are input enable (E0 and E1). The outputs are forced to be HIGH when either input is HIGH. In order to break down any combination of inputs into a set of terms that are all set to "0" except for one term, decoders are just a group of logic gates that are organized in a specified fashion.

write a method that finds the maximum element in an array of double val-ues using the following header: public static double max(double[] array) write a test program that prompts the user to enter ten numbers, invokes this method to return the maximum value, and displays the maximum value. the program must then ask if the user wants to continue with another array of numbers. if the user enters "y", the program will start a new conversion. other-wise, it’ll stop.
Arranging the array's elements in ascending order makes it easy to identify the element with the largest value. Following sorting, the first element will represent the array's smallest element, followed by the second-smallest element, the largest element, and so on.
Find the maximum by iterating through the array first. Together with its index, save this as the first maximum. Now search through the entire array for the second maximum, leaving off the largest element. Find the third largest element by iterating through the array three times and omitting the maximum and second maximum. The goal of the method getresult(int arr[],int n) is to identify the array's maximum and minimum elements with the fewest possible comparisons.
