A sort comparison chart is organized according to this table, where
1. Histogram blue expression is stable, histogram yellow indicates unstable;
2. The number in the middle of the histogram represents the time complexity, the red font indicates the worst, the black font indicates the average complexity;
3. The histogram dashed line represents the worst time co
