Answer:

  1. with(open("numbers.txt")) as file:
  2.    data = file.readlines()  
  3.    runsum = 0
  4.    largest = 0
  5.    
  6.    for x in data:
  7.        if(int(x) > largest):
  8.            largest = int(x)
  9.            runsum += largest  
  10.    
  11.    print(runsum)

Explanation:

The solution code is written in Python 3.

Firstly, open a filestream for numbers.txt (Line 1) and then use readlines method to get every row of data from the text files (Line 2).

Create a variable runsum to hold the running sum of number bigger than the maximum value read up to that iteration in a for loop (Line 3).

Use a for loop to traverse through the read data and then check if the current row of integer is bigger than the maximum value up to that point, set the current integer to largest variable and then add the largest to runsum (Line 6 - 9).

At last display the runsum to console terminal (Line 11).

rjkz [21]

Answer:

import java.util.Scanner;

public class Solution {

   public static void main(String args[]) {      

     Scanner scan = new Scanner(System.in);

     System.out.println("Enter your value");

     int value = scan.nextInt();      

     greaterThanFive(value);

   }  

   public static void greaterThanFive(int userInput){

       System.out.println(userInput > 5);

   }

}

Explanation:

The first line import the Scanner which is use to enable to accept user input.

The class is defined as Solution in the next line. The main method is declared in the next line which signify the beginning of the program.

Then, a scanner object is declared called scan in the next line. Then a prompt is display to the user to input a value. The user input is stored in the variable value. The value is then passed to the method greaterThanFive.

The method greaterThanFive is declared and have just one parameter, the userInput. Inside the method, we output if the userInput is greater than 5 using the logical operator (>).
