Take two String inputs of the same length and merge these by taking one character from each String (starting with the first entered) and alternating. If the Strings are not the same length, the program should print "error".
Sample Run 1:
Enter Strings:
balloon
atrophy
baatlrloopohny
Sample Run 2:
Enter Strings:
terrible
mistake
error
Answer:
Written in Python
print("Enter strings: ")
str1 = input()
str2 = input()
if len(str1) == len(str2):
for i in range(0,len(str1)):
print(str1[i]+str2[i], end='')
else:
print("Error")
Explanation:
Prompts user for two strings
print("Enter strings: ")
The next two lines get the input strings
str1 = input()
str2 = input()
The following if condition checks if length of both strings are the same
if len(str1) == len(str2):
If yes, this iterates through both strings
for i in range(0,len(str1)):
This prints the the characters of both strings, one character at a time
print(str1[i]+str2[i], end='')
If their lengths are not equal, the else condition is executed
else:
print("Error")
import java.util.Scanner;
public class JavaApplication89 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter Strings:");
String word1 = scan.nextLine();
String word2 = scan.nextLine();
String newWord = "";
if (word1.length() != word2.length()){
newWord = "error";
}
else{
for(int i = 0; i < word1.length(); i++){
newWord += word1.charAt(i)+""+word2.charAt(i);
}
}
System.out.println(newWord);
}
}
This is the java solution. I hope this helps!

you are splitting up all your apples equally between 3 people. which statement below will calculate how many apples will be left over ?
a. var leftOver = numApples / 3;
b. var leftOver = 3/ numApples;
c. var leftOver = numApples % 3
d. var leftOver = 3% numApples
Answer:
The correct answer is:
c. var leftOver = numApples % 3
Explanation:
JavaScript uses different operators to perform various mathematical functions. In mathematics, when a number is not completely divisible by other the answer contains the remainder and quotient.
Modulus operator is used in JavaScript to find the remainder.
For example,
20/3 will return the quotient which is 6 while
20%3 will return the remainder which is 2
In the given statement, we have to find the number of remaining apples after being divided into three people
So,
Number of apples mod 3 will give us the number of remaining apples.
Hence,
The correct answer is:
c. var leftOver = numApples % 3
Write the code in python to input a number and print the square root. Use the absolute value function to make sure that if the user enters a negative number, the program does not crash.
Answer:
Code in Python :-
num = float(input("Enter any number : "))
ab = abs(num)
sqrt = float(ab ** 0.5)
print(sqrt)
In python:

I'm not sure how to do these. By the way, it has to be python.
Task 1:
float75 = float(75)
string75 = "75"
# you cannot add together a number and a string because a string has no inherent numerical value like a number does.
Task 2:
num = float(input("Enter a number"))
print(num**2)
Task 3:
num = int(input("Enter an integer: "))
print("When you divide "+str(num)+" by 7, the quotient is "+str(num//7)+" and the remainder is "+str(num%7)+".")
Task 4:
gigs = int(input("How many gigabytes does your flashdrive hold? "))
print("A flashdrive with "+str(gigs)+ " gigabyte(s) holds "+str(gigs*8589934592)+" bit(s).")
For task 4, you might have to change the number 8589934592 to something else. I'm not entirely sure how many bits are in a gigabyte. I hope this helps though.
