Remove Consecutive Duplicates

Given a string ( s ) containing only lowercase English letters, remove all consecutive duplicate characters. In other words, if a character appears consecutively in the string, only the first occurrence should be kept.

For example, given the input string "aaabccddddde", the resulting string will be "abcde".
