@小紬qwq 此题正解线段树,暴力满分才怪呢


by qwopew @ 2019-11-04 19:51:59

@songhongyi 那我为什么有些错了啊QAQ,我知道TLE是超时了

像我这种当年 a+b 还是就着题解写的蒟蒻


by abjfj @ 2019-11-04 19:59:43

    for(i=0; i<b; i++)
    {
        scanf("%d%d%d",&d[i],&e[i],&f[i]);
        for(j=d[i]-1; j<=e[i]-1; j++)
        {
            c[j]+=f[i];
        }
    }

我猜您是想这么写吧
