@Liuzhenyuan 越界?

@ababbjxzt 动态越界?
by FengYuXinMing @ 2023-07-17 19:46:11
@Adorable_ 这么说也对,vector是动态的,按道理来说不会越界啊,可是一般RE越界占多数,所以我也不太明白,没准您学的多,一看没准改好了

@ababbjxzt 别别别,我是个蒟蒻(),dalao都不会得题,我也不会(缩成一团)

@Adorable_ 我也是蒟蒻,您能熟练运用vector,我才刚学,还是个fw(蜷缩在角落)

@ababbjxzt 我也刚学dp()

@ababbjxzt 户关户关,

@Adorable_ 啊?dp?dp我都没学啊?您是学dp才学的vector?我是贪心学的
by FengYuXinMing @ 2023-07-17 20:04:46
@Adorable_ ok
