Given an array of strings words and a character separator, split each string in words by separator.
Return an array of strings containing the new strings formed after the splits, excluding empty strings.
\n\nNotes
\n\nseparator is used to determine where the split should occur, but it is not included as part of the resulting strings.\n
Example 1:
\n\n\nInput: words = ["one.two.three","four.five","six"], separator = "."\nOutput: ["one","two","three","four","five","six"]\nExplanation: In this example we split as follows:\n\n"one.two.three" splits into "one", "two", "three"\n"four.five" splits into "four", "five"\n"six" splits into "six" \n\nHence, the resulting array is ["one","two","three","four","five","six"].\n\n
Example 2:
\n\n\nInput: words = ["$easy$","$problem$"], separator = "$"\nOutput: ["easy","problem"]\nExplanation: In this example we split as follows: \n\n"$easy$" splits into "easy" (excluding empty strings)\n"$problem$" splits into "problem" (excluding empty strings)\n\nHence, the resulting array is ["easy","problem"].\n\n\n
Example 3:
\n\n\nInput: words = ["|||"], separator = "|"\nOutput: []\nExplanation: In this example the resulting split of "|||" will contain only empty strings, so we return an empty array [].\n\n
