java.lang.StringBuilder uses a resizing array to represent a string of length n, with the first character in the string at array index 0 and the last character in the string at array index n - 1. Assume the array length is doubled when full and halved when one-quarter full. For reference, here is a partial API public class StringBuilder StringBuilder() create an empty string void append(char c) add character c to the end of the string void prepend(char c) add character c to the beginning of the string char charAt(int i) return the character at index i and a diagram of the underlying representation for reference. first character last character a[] M. D R M. 1. 2. 3 7. Mark all properties that apply. O e(1) time in the worst case for charAt(). O e(1) time in the worst case for append. Starting from an empty StringBuilder, any sequence of n append operations takes O(n) time in the worst case. Starting from an empty stringBuilder, any sequence of n append and prepend operations takes (n) time in the worst case. OUses (n) memory in the worst case.
