7. We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different
"digits" {0,1,.9). Sometimes though it is useful to write numbers in hexadecimal or base 16. Now there are 16
distinct digits that can be used to form numbers: {0,1,..,9,A,B,C,D,E,F}. So, for example, a 3 digit hexadecimal
number might be 3B8.
(a) How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer
in terms of the additive principle (using either events or sets).
(b) Explain why your answer to the previous part is correct in terms of the multiplicative principle
(using either events or sets). Why do both the additive and multiplicative principles give you the
same answer?
(c) How many 3-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? Explain.
(d) How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)?
Explain.

If the characters e,s,t,u,x,z with the frequency 33,4,20,8,2,32.
Decode the code "10001000111" using the Huffman code. Explain your approach for
decoding. You must follow the same technique covered in the class for generating the
Huffman code.

- Modify the below program that the input values representingfractions are stored with denominators that are positive integers. You cannot require the user to only enter a positive denominator value; the user should not be inconvenienced by such a restriction. For example, whilst values of 1 / -2 are acceptable inputs for a fraction, the output representation should be -1 / 2. Your solution should check the denominator input; if it is negative, swap the sign of both numerator and denominator instance variables. //Import the essential package import java.util.ArrayList; import java.util.Scanner; //Define the class Fraction class Fraction { private int n, d; public Fraction() { //Initialize the values this.n = this.d = 0; } public Fraction(int n, int d) { //Initialize the variables this.n = n; this.d = d; } //Define the getter function getNum() that returns the numerator public int getNum() {…arrow_forwardC++arrow_forwardPlz do it c programming in a basic way as possible and plz (( do it with 1 loop and explen the coods as a comment line))arrow_forward
- Implement function prt_triangle that takes an integer n from the user and prints a n-row triangle using asterisk. It first prompts the message "Enter the size of the triangle:", takes a number from the user as input, and then prints the triangle. You should use the function printf to display the message, allocate memory for one null-terminated strings of length up to 2 characters using char rows[3], and then use the function fgets to read the input into the strings, e.g. fgets(rows, sizeof(rows), stdin). You also need to declare one integer variable nrows using int nrows, and use the function atoi to convert the string rows into the integer nrows. You can use the command man atoi to find more information on how to use the atoi function. A sample execution of the function is as below:Enter the size of the triangle: 5 * ** ** * make sure it is in C not C++arrow_forwardBartleby answered my homework and Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False. Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates. Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following. aaa has duplicatesabc has no duplicates Print a line like one of the above for each of the strings in test_dups. True needs to be defined. I tried to code it but didn't accept and got an error message.arrow_forwardNonearrow_forward
