String Manipulation

UI: button for starting processing, prompt input boxes, 1 or more labels for output string in first prompt input box, number in second prompt input box - the number.

INPUT: Input must be less than or equal to the number of characters in the previously inputted string

PROCESSING: locate the character in the string that is at the position of the number inputted, concatenate the string to itself the number of times as the number inputted, reverse the letters in the string . OUTPUT: The string inputted, the character in the string at the position of the number inputted, the string concatenated the number of times as the number inputted and the string reversed, for example, if frog and 3 is inputted, the three output values would be : frong, o, frogfrogfrog,gorf, **also include a link back to the original page at the bottom of the output.
