Of course, fermaw does have protections against this. For one, he aggressively throttles bursty traffic meaning downloads can go from a few hundred KB/s to 50-ish KB/s. Of course, it will in every case be several times faster than listening and recording anyways.
思路：单调递增栈 + k 控制删除次数。高位越小整体越小，遇更小数字时弹出栈顶大数（仅当 k0）；栈空且当前为 0 则跳过（避免前导零）；若遍历完 k 仍0，从末尾再删 k 位。，详情可参考搜狗输入法2026
