You have to guess which number I picked.</p>\n\n<p>Every time you guess wrong, I will tell you whether the number I picked is higher or lower than your guess.</p>\n\n<p>You call a pre-defined API <code>int guess(int num)</code>, which returns three possible results:</p>\n\n<ul>\n\t<li><code>-1</code>: Your guess is higher than the number I picked (i.e. <code>num > pick</code>).</li>\n\t<li><code>1</code>: Your guess is lower than the number I picked (i.e. <code>num < pick</code>).</li>\n\t<li><code>0</code>: your guess is equal to the number I picked (i.e. <code>num == pick</code>).</li>\n</ul>\n\n<p>Return <em>the number that I picked</em>.</p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> n = 10, pick = 6\n<strong>Output:</strong> 6\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> n = 1, pick = 1\n<strong>Output:</strong> 1\n</pre>\n\n<p><strong>Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> n = 2, pick = 1\n<strong>Output:</strong> 1\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= n <= 2<sup>31</sup> - 1</code></li>\n\t<li><code>1 <= pick <= n</code></li>\n</ul>\n",
