Write the replaceOne method. replaceOne(text, i, n, sub) replaces a segment of text of length n that starts at index i with the replacement string sub. (The length of sub is not necessarily the same as the length n of the segment to be replaced). replace One returns the modified text. Complete the method replaceOne below.

Question 1(a)

• /** Replaces several characters in a given text string,
  * starting at a given index, with a new substring.
  * @param text string to be modified,
  * @param i starting index of replacement
  * @param n number of characters to be replaced
  * @param sub replacement string
  * @return modified text
  * Precondition: i + n <= text.length()
  */
