+ * 722. Remove Comments
+ * https://leetcode.com/problems/remove-comments/
+ * Difficulty: Medium
+ *
+ * Given a C++ program, remove comments from it. The program source is an array where source[i] is the i-th
+ * line of the source code. This represents the result of splitting the original source code string by the
+ * newline character \n.
+ * In C++, there are two types of comments, line comments, and block comments.
+ * The string // denotes a line comment, which represents that it and rest of the characters to the right
+ * of it in the same line should be ignored.
+ * The string /* denotes a block comment, which represents that all characters until the next
+ * (non-overlapping) occurrence of should be ignored.
+ * It is guaranteed that every open block comment will eventually be closed, so /* outside of a line or block
+ * comment always starts a new comment.
+ * Finally, implicit newline characters can be deleted by block comments.
+ * After removing the comments from the source code, return the source code in the same format.
+ */
