"content": "<p>Given a C++ program, remove comments from it. The program source is an array of strings <code>source</code> where <code>source[i]</code> is the <code>i<sup>th</sup></code> line of the source code. This represents the result of splitting the original source code string by the newline character <code>'\\n'</code>.</p>\n\n<p>In C++, there are two types of comments, line comments, and block comments.</p>\n\n<ul>\n\t<li>The string <code>"//"</code> denotes a line comment, which represents that it and the rest of the characters to the right of it in the same line should be ignored.</li>\n\t<li>The string <code>"/*"</code> denotes a block comment, which represents that all characters until the next (non-overlapping) occurrence of <code>"*/"</code> should be ignored. (Here, occurrences happen in reading order: line by line from left to right.) To be clear, the string <code>"/*/"</code> does not yet end the block comment, as the ending would be overlapping the beginning.</li>\n</ul>\n\n<p>The first effective comment takes precedence over others.</p>\n\n<ul>\n\t<li>For example, if the string <code>"//"</code> occurs in a block comment, it is ignored.</li>\n\t<li>Similarly, if the string <code>"/*"</code> occurs in a line or block comment, it is also ignored.</li>\n</ul>\n\n<p>If a certain line of code is empty after removing comments, you must not output that line: each string in the answer list will be non-empty.</p>\n\n<p>There will be no control characters, single quote, or double quote characters.</p>\n\n<ul>\n\t<li>For example, <code>source = "string s = "/* Not a comment. */";"</code> will not be a test case.</li>\n</ul>\n\n<p>Also, nothing else such as defines or macros will interfere with the comments.</p>\n\n<p>It is guaranteed that every open block comment will eventually be closed, so <code>"/*"</code> outside of a line or block comment always starts a new comment.</p>\n\n<p>Finally, implicit newline characters can be deleted by block comments. Please see the examples below for details.</p>\n\n<p>After removing the comments from the source code, return <em>the source code in the same format</em>.</p>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> source = ["/*Test program */", "int main()", "{ ", " // variable declaration ", "int a, b, c;", "/* This is a test", " multiline ", " comment for ", " testing */", "a = b + c;", "}"]\n<strong>Output:</strong> ["int main()","{ "," ","int a, b, c;","a = b + c;","}"]\n<strong>Explanation:</strong> The line by line code is visualized as below:\n/*Test program */\nint main()\n{ \n // variable declaration \nint a, b, c;\n/* This is a test\n multiline \n comment for \n testing */\na = b + c;\n}\nThe string /* denotes a block comment, including line 1 and lines 6-9. The string // denotes line 4 as comments.\nThe line by line output code is visualized as below:\nint main()\n{ \n \nint a, b, c;\na = b + c;\n}\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> source = ["a/*comment", "line", "more_comment*/b"]\n<strong>Output:</strong> ["ab"]\n<strong>Explanation:</strong> The original source string is "a/*comment\\nline\\nmore_comment*/b", where we have bolded the newline characters. After deletion, the implicit newline characters are deleted, leaving the string "ab", which when delimited by newline characters becomes ["ab"].\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= source.length <= 100</code></li>\n\t<li><code>0 <= source[i].length <= 80</code></li>\n\t<li><code>source[i]</code> consists of printable <strong>ASCII</strong> characters.</li>\n\t<li>Every open block comment is eventually closed.</li>\n\t<li>There are no single-quote or double-quote in the input.</li>\n</ul>\n",
