Question

#You may modify the lines of code above, but don't move them! #When you Submit your code, we'll change these lines to #assign different values to the variables. #There's an easy way to do this exercise, and a hard way. For #a hint on the easier way, revisit the sample answers for the #previous coding exercise. # #Above we've created a variable called mystery_string. Write #some code that will print the first letter of the string on #the first line, the first two letters on the second line, #the first three letters on the third line, etc., until it #prints the entire string on the last line. #

Answer 1

Answer:

The solution code is written in Python:

1. mystery_string = "Programming"
2. output = ""
4. for x in mystery_string:
5.    output += x  
6.    print(output)

Explanation:

Firstly, create a variable mystery_string to hold a random string (Line 1).

Create an output variable to hold an output string (Line 2).

Create a for-loop to traverse the mystery_string character by character (Line 4). In the iteration, get a character from the mystery_string, and concatenate it with output string (Line 5). Print the output string (Line 6) before proceed to the next iteration.
