我有如下图所示的图：
该图像是使用以下代码生成的：
\documentclass[tikz, border=3mm]{standalone}
\usetikzlibrary{arrows.meta,chains,matrix,decorations.pathreplacing}
\begin{document}
\begin{tikzpicture}[
node distance=0pt,
start chain = A going right,
arrow/.style = {draw=#1,-{Stealth[]},
shorten >=1mm, shorten <=1mm}, % styles of arrows
arrow/.default = black,
X/.style = {rectangle, draw,% styles of nodes in string (chain)
minimum width=2ex, minimum height=3ex,
outer sep=0pt, on chain},
B/.style = {decorate,
decoration={brace, amplitude=5pt,
pre=moveto,pre length=1pt,post=moveto,post length=1pt,
raise=1mm,
#1}, % for mirroring of brace, if necessary
thick},
B/.default = mirror, % by default braces are mirrored
]
\foreach \i in {1,0,0,0,1,1,
2,0,3,4,1,2}% <-- content of nodes
\node[X] {\i};

但是，我想替换箭类似于下面给出的图片。这些图片是从 Google 图片中收集的。

非常感谢任何帮助或想法。

由于start width和end width从未指定，我创建了\maxlinewidth=2pt最终的线宽并调整了算法。
