[说明]

下面流程图的功能是：在已知字符串A中查找特定字符串B，如果存在，则输出B串首字符在A串中的位置，否则输出-1。设串A由n个字符A(0)、A(1)、…、A(n-1)组成，串B由m个字符B(0)、B(1)、…、B(m-1)组成，其中n≥m＞0。在串A中查找串B的基本算法如下：从串A的首字符A(0)开始，取子串A(0)A(1)…i(m-1)与串B比较；若不同，则再取子串A(1)A(2)…A(m)与串B比较，以此类推。

例如，字符串“CABBRFFD”中存在字符子串“BRF”(输出3)，不存在字符子串“RFD”(输出-1)。

在流程图中，i用于访问串A中的字符(i=0，1，…，n-1)，j用于访问串B中的字符(j=0，1，…，m-1)。在比较A(i)A(i+1)…A(i+m-1)与B(0)B(1)…B(m-1)时，需要对A(i)与B(0)、A(i+1)与B(1)、…、A(i+j)与B(j)、…逐对字符进行比较。若发现不同，则需要取下一个子串进行比较，以此类推。
