The customer has requested a specific color, and we need to<br \/>\n        create a cocktail that matches that color using various ingredients.\n    <\/p>\n<p>\n        The following input is given:\n    <\/p>\n<ul>\n<li> The number of ingredients N (1 &lt;= N &lt;= 100)<\/li>\n<li> An array of colors representing each ingredient (colors are provided as strings)<\/li>\n<li> The color requested by the customer targetColor (string)<\/li>\n<\/ul>\n<p>\n        We need to determine whether we can make a cocktail of the requested color.<br \/>\n        If it can be made, we should output &#8220;Possible&#8221;; otherwise, we output &#8220;Impossible.&#8221;\n    <\/p>\n<h2>Input Example<\/h2>\n<pre>\n        5\n        \"red\", \"blue\", \"green\", \"yellow\", \"red\"\n        \"purple\"\n    <\/pre>\n<h2>Output Example<\/h2>\n<pre>Possible<\/pre>\n<h2>Algorithm Design<\/h2>\n<p>\n        To solve this problem, we need to perform a few simple operations.<br \/>\n        First, we must check all the given colors to see if any match the customer&#8217;s request.<br \/>\n        We can approach it as follows:\n    <\/p>\n<ol>\n<li>Search the array of colors to see if it contains a color that matches the customer&#8217;s request.<\/li>\n<li>If a matching color is found, print &#8220;Possible&#8221; and terminate the iteration.<\/li>\n<li>If no matching color is found after checking all colors, print &#8220;Impossible.&#8221;<\/li>\n<\/ol>\n<h2>Code Writing<\/h2>\n<p>\n        Now, let&#8217;s write Kotlin code based on the algorithm designed above.<br \/>\n        Using Kotlin&#8217;s concise syntax, we can implement the solution to the problem as follows.\n    <\/p>\n<pre>\n        fun canMakeCocktail(colors: Array<String>, targetColor: String): String {\n            for (color in colors) {\n                if (color == targetColor) {\n                    return \"Possible\"\n                }\n            }\n            return \"Impossible\"\n        }\n\n        fun main() {\n            val colors = arrayOf(\"red\", \"blue\", \"green\", \"yellow\", \"red\")\n            val targetColor = \"purple\"\n            println(canMakeCocktail(colors, targetColor))\n        }\n    <\/pre>\n<h2>Code Explanation<\/h2>\n<p>\n        In the code above, the <code>canMakeCocktail<\/code> function takes two parameters.<br \/>\n        The first parameter is an array of colors, and the second parameter is the color requested by the customer.<br \/>\n        It uses a <code>for<\/code> loop to iterate through the array, checking for a match with the requested color.\n    <\/p>\n<p>\n        If a matching color is found, it returns &#8220;Possible&#8221; and terminates.<br \/>\n        If no matches are found after checking all colors, it returns &#8220;Impossible.&#8221;<br \/>\n        The <code>main<\/code> function sets the given array of colors and the requested color,<br \/>\n        and calls the <code>canMakeCocktail<\/code> function to output the result.\n    <\/p>\n<h2>Test Cases<\/h2>\n<p>\n        Now, let&#8217;s test the code.
