1313 - Decompress Run-Length Encoded List\. Easy We are given a list `nums` of integers representing a list compressed with run-length encoding. Consider each adjacent pair of elements `[freq, val] = [nums[2*i], nums[2*i+1]]` (with `i >= 0`). For each such pair, there are `freq` elements with value `val` concatenated in a sublist. Concatenate all the sublists from left to right to generate the decompressed list. Return the decompressed list. **Example 1:** **Input:** nums = [1,2,3,4] **Output:** [2,4,4,4] **Explanation:** The first pair [1,2] means we have freq = 1 and val = 2 so we generate the array [2]. The second pair [3,4] means we have freq = 3 and val = 4 so we generate [4,4,4]. At the end the concatenation [2] + [4,4,4] is [2,4,4,4]. **Example 2:** **Input:** nums = [1,1,2,3] **Output:** [1,3,3] **Constraints:** * `2 <= nums.length <= 100` * `nums.length % 2 == 0` * `1 <= nums[i] <= 100`
