Write a short program using Python that will:
Alexxx [7]

Answer:

// program in Python to check perfect number

#function to find number is perfect or not

def is_Perfect_Number(n):

   #total variable

   tot = 1

   i = 2

   #sum of all divisor of number

   while i*i<=n:

       if n%i==0:

           tot = tot + i + n/i

       if tot == n and n != 1:

           return 1

       i = i+1  

   return 0

#read until user enter a perfect number

while True:

   #read integer

   num = int(input("Input an integer: "))

   #call the function

   if(is_Perfect_Number(num)):

       print(num,"is perfect number")

       #if perfect number break

       break

   else:

       print(num,"is not a perfect number")

       #ask again

   print("try again.")

Explanation:

Read number from user and then call the function is_Perfect_Number() with  parameter "num".This will find the sum of all divisor of number.If sum is  equal to number then it will return 1 else return 0.If the number is not  perfect then it will again ask to enter a number until user enter a perfect  number.

Output:

Input an integer: 24

24 is not a perfect number                                                                                                

try again.                                                                                                                

Input an integer: 28                                                                                                      

28 is perfect number

Write a static method called bothStart that allows the user to input two Strings and returns the String that is the longest subs
marishachu [46]

Answer:

  1.    public static String bothStart(String text1, String text2){
  2.        String s = "";
  3.        if(text1.length() > text2.length()) {
  4.            for (int i = 0; i < text2.length(); i++) {
  5.                if (text1.charAt(i) == text2.charAt(i)) {
  6.                    s += text1.charAt(i);
  7.                }else{
  8.                    break;
  9.                }
  10.            }
  11.            return s;
  12.        }else{
  13.            for (int i = 0; i < text1.length(); i++) {
  14.                if (text1.charAt(i) == text2.charAt(i)) {
  15.                    s += text1.charAt(i);
  16.                }else{
  17.                    break;
  18.                }
  19.            }
  20.            return s;
  21.        }
  22.    }

Explanation:

Let's start with creating a static method <em>bothStart()</em> with two String type parameters, <em>text1 </em>&<em> text2</em> (Line 1).  

<em />

Create a String type variable, <em>s,</em> which will hold the value of the longest substring that both inputs start with the same character (Line 2).

There are two possible situation here: either <em>text1 </em>longer than<em> text2 </em>or vice versa. Hence, we need to create if-else statements to handle these two position conditions (Line 4 & Line 13).

If the length of<em> text1</em> is longer than <em>text2</em>, the for-loop should only traverse both of strings up to the length of the <em>text2 </em>(Line 5). Within the for-loop, we can use<em> charAt()</em> method to extract individual character from the<em> text1</em> & <em>text2 </em>and compare with each other (Line 15). If they are matched, the character should be joined with the string s (Line 16). If not, break the loop.

The program logic from (Line 14 - 20) is similar to the code segment above (Line 4 -12) except for-loop traverse up to the length of <em>text1 .</em>

<em />

At the end, return the s as output (Line 21).
