<p>Given two arrays of integers <code>nums</code> and <code>index</code>. Your task is to create <em>target</em> array under the following rules:</p> <ul> <li>Initially <em>target</em> array is empty.</li> <li>From left to right read nums[i] and index[i], insert at index <code>index[i]</code> the value <code>nums[i]</code> in <em>target</em> array.</li> <li>Repeat the previous step until there are no elements to read in <code>nums</code> and <code>index.</code></li> </ul> <p>Return the <em>target</em> array.</p> <p>It is guaranteed that the insertion operations will be valid.</p> <p> </p> <p><strong class="example">Example 1:</strong></p> <pre> <strong>Input:</strong> nums = [0,1,2,3,4], index = [0,1,2,2,1] <strong>Output:</strong> [0,4,1,3,2] <strong>Explanation:</strong> nums index target 0 0 [0] 1 1 [0,1] 2 2 [0,1,2] 3 2 [0,1,3,2] 4 1 [0,4,1,3,2] </pre> <p><strong class="example">Example 2:</strong></p> <pre> <strong>Input:</strong> nums = [1,2,3,4,0], index = [0,1,2,3,0] <strong>Output:</strong> [0,1,2,3,4] <strong>Explanation:</strong> nums index target 1 0 [1] 2 1 [1,2] 3 2 [1,2,3] 4 3 [1,2,3,4] 0 0 [0,1,2,3,4] </pre> <p><strong class="example">Example 3:</strong></p> <pre> <strong>Input:</strong> nums = [1], index = [0] <strong>Output:</strong> [1] </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length, index.length <= 100</code></li> <li><code>nums.length == index.length</code></li> <li><code>0 <= nums[i] <= 100</code></li> <li><code>0 <= index[i] <= i</code></li> </ul>
