"content": "<p>You are given an integer array <code>target</code> and an integer <code>n</code>.</p>\n\n<p>You have an empty stack with the two following operations:</p>\n\n<ul>\n\t<li><strong><code>"Push"</code></strong>: pushes an integer to the top of the stack.</li>\n\t<li><strong><code>"Pop"</code></strong>: removes the integer on the top of the stack.</li>\n</ul>\n\n<p>You also have a stream of the integers in the range <code>[1, n]</code>.</p>\n\n<p>Use the two stack operations to make the numbers in the stack (from the bottom to the top) equal to <code>target</code>. You should follow the following rules:</p>\n\n<ul>\n\t<li>If the stream of the integers is not empty, pick the next integer from the stream and push it to the top of the stack.</li>\n\t<li>If the stack is not empty, pop the integer at the top of the stack.</li>\n\t<li>If, at any moment, the elements in the stack (from the bottom to the top) are equal to <code>target</code>, do not read new integers from the stream and do not do more operations on the stack.</li>\n</ul>\n\n<p>Return <em>the stack operations needed to build </em><code>target</code> following the mentioned rules. If there are multiple valid answers, return <strong>any of them</strong>.</p>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> target = [1,3], n = 3\n<strong>Output:</strong> ["Push","Push","Pop","Push"]\n<strong>Explanation:</strong> Initially the stack s is empty. The last element is the top of the stack.\nRead 1 from the stream and push it to the stack. s = [1].\nRead 2 from the stream and push it to the stack. s = [1,2].\nPop the integer on the top of the stack. s = [1].\nRead 3 from the stream and push it to the stack. s = [1,3].\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> target = [1,2,3], n = 3\n<strong>Output:</strong> ["Push","Push","Push"]\n<strong>Explanation:</strong> Initially the stack s is empty.

The last element is the top of the stack.\nRead 1 from the stream and push it to the stack. s = [1].\nRead 2 from the stream and push it to the stack. s = [1,2].\nSince the stack (from the bottom to the top) is equal to target, we stop the stack operations.\nThe answers that read integer 3 from the stream are not accepted.\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= target.length <= 100</code></li>\n\t<li><code>1 <= n <= 100</code></li>\n\t<li><code>1 <= target[i] <= n</code></li>\n\t<li><code>target</code> is strictly increasing.</li>\n</ul>\n",
