当输入为 ‘cbabc’ 时，下列程序的输出结果为？s1 = raw_input() index = 0 s2 = '' while index [ len(s1) - 1: if s1[index] ] s1[index + 1]: s2 += s1[index] else: s2 = s2 * 2 index += 1 print s2

写出下面程序的输出结果 publicclassTestjava{ publicstaticvoidmain(String[]args){ Stringstr="abbaefabbewbvwabbswgfga"; System.out.println("count="+getSubCount(str,"abb")); } publicstaticintgetSubCount(Stringstr,Stringkey){ intcount=0; intindex=0; while((index=str.indexOf(key,index))!=-1){ System.out.println("index="+index); index=index+key.length(); count++; } returncount; } }
