@[ISU152_YYDS](/user/933802) 和我的对一下吧,你的pushdown写的着实抽象（

@[zyh0516_lucky](/user/746930) 请问区别在什么位置，谢谢

你update1里面%成k了
by Paradise_Lost @ 2023-12-29 21:41:01
@[ISU152_YYDS](/user/933802) 我这么长代码就是改了update1中的%k为%m

@[rnfmabj5114](/user/917683) 楼主想要参考代码可以看题解。而且只是写法不同而已，楼主代码哪里抽象了？

@[zyh0516_lucky](/user/746930) @[Paradise_Lost](/user/688649) 谢谢，关了

@[zyh0516_lucky](/user/746930) 我感觉代码太长了蛮抽象的,写个函数不就缩了好多嘛,还好找错
