Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly one space (i. e., if a number appears multiple times, it is displayed only once).

(hint: read a number and store it to an array if it is new. if the number is already in the array, ignore it.)

after the input, the array contains the distinct numbers in the order of their input.

The program to this question can be given as:

Program:

//import package.

import java.util.*;

public class Main //defining the class

{

public static void main(String[] args) //defining main method

{

Scanner ob = new Scanner(System.in); //creating scanner class object.

int[] a = new int[10];//define array.

int number,counts= 0,i;//define variable.

System.out.print("Enter numbers: "); //message.

for (i = 0; i < 10; i++) //loop

{

number=ob.nextInt();

if (isDistinct(a,number))

{

a[counts] = number;//assign value in array

counts++;// Increment count

}

System.out.println("The distinct numbers is :" + counts);

System.out.print("The distinct number are :");

for (i = 0; i <a.length; i++)//loop

{

if (a[i] > 0)

{

System.out.print(" " +a[i]);//print array.

}

System.out.println();

}

public static boolean isDistinct(int[] array, int num)//defining method

{

for (int i = 0; i < array.length; i++)//loop for check number

{

if (num == array[i]) //check condition

{

return false; //return value false.

}

return true; //return value true

}

Output:

First time run:

Enter ten numbers: 1 2 3 4 5 6 7 8 9 10

The number of distinct numbers is 10

The distinct numbers are 1 2 3 4 5 6 7 8 9 10

Second time run:

Enter numbers: 2 3 5 8 7 4 3 2 1 2

The distinct numbers is :7

The distinct number are : 2 3 5 8 7 4 1

Explanation:

The description of the above java code can be given as:

In the above java code, a class is defined that is main inside a class-main function is defined in the main function firstly creating a scanner class object that is "ob" then define variables and array that are number, counts and a[]. To inserts array elements we use a loop. In the loop, we use integer variable number and define a condition in if block passes a function that check value count total value. In the second loop, we check the condition that array elements value is greater than 0 and print all array elements. The isDistinct function checks in the array two values are not the same. if the values are the same it will return false value because this function is the boolean type that returns an only boolean value.

For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. after converting to the postfix expression, the program should evaluate the expression from the postfix and display the result. what should you submit? write all the code in a single file and upload the .c file. compliance with rules: ucf golden rules apply towards this assignment and submission. assignment rules mentioned in syllabus, are also applied in this submission. the ta and instructor can call any students for explaining any part of the code in order to better assess your authorship and for further clarification if needed. problem: we as humans write math expression in infix notation, e. g. 5 + 2 (the operators are written in-between the operands). in computer's language, however, it is preferred to have the operators on the right side of the operands, ie. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix write a program that takes an "infix" expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % ( example infix expression: (7-3)/(2+2) postfix expression: 7 3 2 2 result: rubric: 1) if code does not compile in eustis server: 0. 2) checking the balance of the parenthesis: 2 points 3) incorrect postfix expression per test case: -2 points 4) correct postfix but incorrect evaluation per test case: -i points 5) handling single digit inputs: maximum 11 points 6) handling two-digit inputs: 100 percent (if pass all test cases)
