- (Same-number subsequence) JAVA Class Name: Exercise22_05 Write an O(n) program that prompts the user to enter a sequence of integers ending with 0 and finds the longest subsequence with the same number. Sample Run 1 Enter a series of numbers ending with 0:2 4 4 8 8 8 8 2 4 4 0The longest same number sequence starts at index 3 with 4 values of 8 Sample Run 2 Enter a series of numbers ending with 0: 34 4 5 4 3 5 5 3 2 0 The longest same number sequence starts at index 5 with 2 values of 5arrow_forward(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward(IN C LANGUAGE) Binary-Decimal / Decimal Binary . Between 0 and 255 a number will be decided randomly by computer. Then asks to user 3 times a random digit of binary value of the that number. If user enters wrong number for a digit program will select another random number and ask random times random digit. For example: Computer selected number as 163 ( Which is 10100011) What is the digit 2 (question 1/3) :User enter 1 CorrectWhat is the digit 4 (question 2/3) : User enter 0 CorrectWhat is the digit 7 (question 3/3) : User enter 0 CorrectUser finished the quest with 3 input .arrow_forward
- (Sum the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14.arrow_forward3. (Tabular Output) Write a Java application that uses looping to print the following table of(Exercise 4.22) values: 1 4 9 16 25 1 8 27 64 125 1 16 81 256 625arrow_forward(Financial application: payroll) Write a Java program that reads the following information and prints a payroll statement:arrow_forward
- (Computer-Assisted Instruction: Reducing Student Fatigue) One problem in CAI environments is student fatigue. This can be reduced by varying the computer’s responses to hold the student’s attention. Modify the program of Exercise 6.57 so that various comments are displayed for each answer as follows: Possible responses to a correct answer: Very good!Excellent!Nice work!Keep up the good work! Possible responses to an incorrect answer: No. Please try again.Wrong. Try once more.Don't give up!No. Keep trying.Use random-number generation to choose a number from 1 to 4 that will be used to select one of the four appropriate responses to each correct or incorrect answer. Use a switch statement to issue the responses. ------------------------------ EXERCISE 6.57 CODE: ----------------------------- //Name: IhabAtouf//Date:02/23/2023// exercise 6.57 on page 281//program description: create computer-assisted instruction (CAI) program that help students master thier math skills in…arrow_forward(Demonstrate cancellation errors) A cancellation error occurs when you are manipulating a very large number with a very small number. The large number may cancel out the smaller number. For example, the result of 100000000.0 + 0.000000001 is equal to 100000000.0. To avoid cancellation errors and obtain more accurate results, carefully select the order of computation. For example, in computing the following series, you will obtain more accurate results by comput- ing from right to left rather than from left to right: 1 1 1 1+ + 3 + ... 2 п Write a program that compares the results of the summation of the preceding series, computing from left to right and from right to left with n = 50000.arrow_forward(Limitations of Floating-Point Numbers for Monetary Amounts) Section 4.6 cautionedabout using floating-point values for monetary calculations. Try this experiment: Create a floatvariable with the value 1000000.00. Next add to that variable the literal float value 0.12f. Displaythe result using printf and the conversion specifier "%.2f". What do you get?arrow_forward

Write a program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that “The equation has no solution.”arrow_forward(True or False) Seven different positive integers are randomly chosen between 1 and 2022 (including 1 and 2022).There must be a pair of these integers has a difference that is a multiple of 6.arrow_forward
