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。
ultimately failed... a surprising outcome, given their dominance in the machines，这一点在im钱包官方下载中也有详细论述

Greyscale rendering is deliberate. Gupta et al. (2023, “GlyphNet”) found that greyscale outperforms colour for glyph comparison because extreme contrast preserves edge detail through resize. No image augmentation either: flipping or rotating characters creates unrealistic glyphs.
