<p>Given an array of strings <code>words</code> and a character <code>separator</code>, <strong>split</strong> each string in <code>words</code> by <code>separator</code>.</p> <p>Return <em>an array of strings containing the new strings formed after the splits, <strong>excluding empty strings</strong>.</em></p> <p><strong>Notes</strong></p> <ul> <li><code>separator</code> is used to determine where the split should occur, but it is not included as part of the resulting strings.</li> <li>A split may result in more than two strings.</li> <li>The resulting strings must maintain the same order as they were initially given.</li> </ul> <p> </p> <p><strong class="example">Example 1:</strong></p> <pre> <strong>Input:</strong> words = ["one.two.three","four.five","six"], separator = "." <strong>Output:</strong> ["one","two","three","four","five","six"] <strong>Explanation: </strong>In this example we split as follows: "one.two.three" splits into "one", "two", "three" "four.five" splits into "four", "five" "six" splits into "six" Hence, the resulting array is ["one","two","three","four","five","six"].</pre> <p><strong class="example">Example 2:</strong></p> <pre> <strong>Input:</strong> words = ["$easy$","$problem$"], separator = "$" <strong>Output:</strong> ["easy","problem"] <strong>Explanation:</strong> In this example we split as follows: "$easy$" splits into "easy" (excluding empty strings) "$problem$" splits into "problem" (excluding empty strings) Hence, the resulting array is ["easy","problem"]. </pre> <p><strong class="example">Example 3:</strong></p> <pre> <strong>Input:</strong> words = ["|||"], separator = "|" <strong>Output:</strong> [] <strong>Explanation:</strong> In this example the resulting split of "|||" will contain only empty strings, so we return an empty array []. </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= words.length <= 100</code></li> <li><code>1 <= words[i].length <= 20</code></li> <li>characters in <code>words[i]</code> are either lowercase English letters or characters from the string <code>".,|$#@"</code> (excluding the quotes)</li> <li><code>separator</code> is a character from the string <code>".,|$#@"</code> (excluding the quotes)</li> </ul>
