Rhythmic Block Reversal

Given a linked list and an initial block size of 1, reverse the first block. Then, increment the block size to 2 and reverse the next 2 nodes. Then, increment to 3 and reverse the next 3 nodes, and so on. If the remaining nodes are fewer than the current block size, reverse all of them. Return the modified list. Example: Input: 1 2 3 4 5 6 7 8 9 10 - Block 1 (size 1): [1] -> [1] - Block 2 (size 2): [2, 3] -> [3, 2] - Block 3 (size 3): [4, 5, 6] -> [6, 5, 4] - Block 4 (size 4): [7, 8, 9, 10] -> [10, 9, 8, 7] Output: 1 3 2 6 5 4 10 9 8 7
