29 - Divide Two Integers.<p>Medium</p> <p>Given two integers <code>dividend</code> and <code>divisor</code>, divide two integers <strong>without</strong> using multiplication, division, and mod operator.</p> <p>The integer division should truncate toward zero, which means losing its fractional part. For example, <code>8.345</code> would be truncated to <code>8</code>, and <code>-2.7335</code> would be truncated to <code>-2</code>.</p> <p>Return <em>the <strong>quotient</strong> after dividing</em> <code>dividend</code> <em>by</em> <code>divisor</code>.</p> <p><strong>Note:</strong> Assume we are dealing with an environment that could only store integers within the <strong>32-bit</strong> signed integer range: <code>[\u22122³¹, 2³¹ \u2212 1]</code>. For this problem, if the quotient is <strong>strictly greater than</strong> <code>[2³¹ \u2212 1]</code>, then return <code>[2³¹ \u2212 1]</code>, and if the quotient is <strong>strictly less than</strong> <code>[-2³¹ \u2212 1]</code>, then return <code>[-2³¹ \u2212 1]</code>.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> dividend = 10, divisor = 3</p> <p><strong>Output:</strong> 3</p> <p><strong>Explanation:</strong> 10/3 = 3.33333.. which is truncated to 3.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> dividend = 7, divisor = -3</p> <p><strong>Output:</strong> -2</p> <p><strong>Explanation:</strong> 7/-3 = -2.33333.. which is truncated to -2.</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> dividend = 0, divisor = 1</p> <p><strong>Output:</strong> 0</p> <p><strong>Example 4:</strong></p> <p><strong>Input:</strong> dividend = 1, divisor = 1</p> <p><strong>Output:</strong> 1</p> <p><strong>Constraints:</strong></p> <ul> <li><code>-2³¹ <= dividend, divisor <= 2³¹ - 1</code></li> <li><code>divisor != 0</code></li> </ul>
