  • 第1题:

    编写函数,isValue,它的功能是:求以下数列中满足t(K)=1的最小的k,结果由函数返回。其中数列t(n)的定义为:

    t(0)=m(m为给定正整数,m<=300)

    t(n+1)=t(n)/2 (当t(n)为偶数时)

    或t(n+1)=3*t(n)+1(当t(n)为奇数时)

    最后调用函数writeDat()读取50个数据m,分别得出结果且把结果输出到文件out.dar中。

    例如:当t=299时,函数值为117。

    已知对于m<=300,结果k不超过300

    部分源程序已给出。

    请勿改动主函数main()和写函数writeDat()的内容。

    include<stdio. h>

    int jsValue(int m)

    {

    main ( )

    {

    int m;

    m=300;

    printf ("m=%d, k-%d\n", m, jsValue (m));

    writeDat ( );

    writeDat ( )

    {

    FILE *in, *out;

    int i,m,s;

    in= fopen ( "in. dar" , "r" );

    ut=f open ( "out. dar" , "w" );

    for (i=0; i<50; i++) {

    fscanf (in, "%d", &m);

    s=jsValue (m);

    printf( "%d\n", s );

    fprintf (out, "%d\n" , s );

    }

    fclose (in);

    fclose (out);


    正确答案:int isValue(int m) { /*初值t(0)=m*/ int fn=m k=0; /*t(k) != 1 求t(k+1)*/ while ( fn>) { if (fn%2==1) /*t(k)为奇数*/ { fn-3*fn+1; } else /*t (k) 为偶数*/ { fn=fn/2; } k++; } /*t (k) ==1 返回 k*/ return k; }
    int isValue(int m) { /*初值t(0)=m*/ int fn=m, k=0; /*t(k) != 1, 求t(k+1)*/ while ( fn>) { if (fn%2==1) /*t(k)为奇数*/ { fn-3*fn+1; } else /*t (k) 为偶数*/ { fn=fn/2; } k++; } /*t (k) ==1, 返回 k*/ return k; } 解析:类型:序列计算。
    关键点:分析序列定义,选择合适的方法生成和存储序列或序列中的特定值。
    根据序列定义,以及题目的输出要求,可选择保存序列中的所有值,也可以只保留与当前项计算相关的几项,采用递推的方式进行计算。
    对于某些特殊序列,还可以求出通项公式,利用公式直接计算。
    此题只需要保存当前项,根据当前项计算下一项。

  • 第3题:

    请阅读下面程序 publicclassThreadTest{ publicstaticvoidmain(Stringargs[])throwsException{ inti=0; Hellot=newHello(); ______, while(true){ System.out.println("GoodMoming"+i++); if(i==2&&t.isAlive()){ System.out.println("MainwaitingforHello!"); t.join();//等待t运行结束 } if(i==5)break;} } } classHelloextendsThread{ inti; publicvoidrun(){ while(true){ System.out.println("Hello"+i++); if(i==5)break;}}} 为使该程序正确执行, 下划线处的语句应是( )。

    A.t.sleep()

    B.t.yield()

    C.t.interrupt()

    D.t.start()


    正确答案:D
    解析: 程序中通过继承Thread类来创建线程,而Java中新创建的线程不会自动运行,必须调用线程的start()方法,才能运行该线程。
