    下列程序段的时间复杂度为()。for(i=0；i＜m；i++)for(j=0；j＜t；j++)e[i][j]=0；for(i=0；i＜m；i++)for(j=0；j＜t；j++)for(k=0；k＜n；k++)c[i][j]_c[i][j]+a[i][k]×b[k][j]；

    B.O(m+n+t)
    C.O(m×t+n)
    D.O(m+n×t)

    答案：A
    解析：
    在程序段中，有两段循环程序，第一段是一个双层嵌套循环，另一个是三层嵌套循环，所以基本操作是c[i][j]=c[i][j]+a[i][k]×b[k][j]，此基本操作共执行m×t×n次。
