code如下：

//Longest common sequence, dynamic programming method

void FindLCS(char *str1, char *str2)
{
	if(str1 == NULL || str2 == NULL)
		return;
	int length1 = strlen(str1)+1;
	int length2 = strlen(str2)+1;
	int **csLength,**direction;//two arrays to record the length and direction
	int i,j,maxLength=0,maxI=0,maxJ=0;
	csLength = (int **)new int[length2];
	for(i=0; i<length1; i++)
		csLength[i] = (int *)new int[length1];
	for(i=0;i<length2;i++)
		for(j=0;j<length1;j++)
			csLength[i][j] = 0;
	direction = (int **)new int[length2];
	for(i=0; i<length1; i++)
		direction[i] = (int *)new int[length1];
	for(i=0;i<length2;i++)

	//the output is in reverse order
