for (int i = 0; i < sentenceN; i++)
{
for (int j = 0; j < array[i].Length; j++)
{
for (int x = 0; x < sentenceN; x++)
{
for (int y = 0; y < array.Length[x]; y++)
{
if (array[i][j] == array[x][y])
array[x][y] = containN++; //这里要如何存储最后的值，如果放进二维数组的话，就是覆盖，但后面遍历时还要用到。？？？
break;
}
}
}
}
array是个动态二维数组，里面放的是一个个的词语。这个二维数组的第一维是句子。
这段程序的目的是便利每一个句子，找到一个词在多少个句子中出现。
最后统计包含这个特定词语句子的个数。
===================================================================================
本来我想把统计后的数子放进原数组，但这样的话，下一次遍历的时候原先的数组就被覆盖了。
所以我想开辟一个新的动态数组，其大小跟array一样，专门用来存放containN++的值，也就是包含词语句子的个数。
请问我应该怎么做？如何定义这个数组
谢谢！
并输出出现频率为75%的单词
