第⼀题：输⼊字符串长度len1，字符串s1，字符串长度len2，字符串s2。从后向前⽐较，以最短字符串为标准，输出不同的元素的个数。例如:  输⼊：s1="1,3,5"  len1=3        s2="2,4,1,7,5"  len2=5
输出：1

[java] ：
public class HuaWeiTest {
public static void main(String[] args) {
String s1 = "1,3,5";
String s2 = "2,4,1,7,5";
int len1 = 3;
int len2 = 5;
HuaWeiTest hwt = new HuaWeiTest();
System.out.DiffNum(len1, s1, len2, s2));
}
public int getDiffNum(int len1, String s1, int len2, String s2)  {
int count = 0;
int len = 0;
String[] arr1 = s1.split(",");
String[] arr2 = s2.split(",");
if(len1 > len2) len = len2;
else len = len1;
for(int i=0;i
if(!arr1[len1-i-1].equals(arr2[len2-i-1])) {
count ++;
}
}
return count;
}
}
public class HuaWeiTest {
public static void main(String[] args) {
String s1 = "1,3,5";
String s2 = "2,4,1,7,5";

int len1 = 3;
int len2 = 5;
HuaWeiTest hwt = new HuaWeiTest();
System.out.DiffNum(len1, s1, len2, s2));
}
public int getDiffNum(int len1, String s1, int len2, String s2)  {
int count = 0;
int len = 0;
String[] arr1 = s1.split(",");
String[] arr2 = s2.split(",");
if(len1 > len2) len = len2;
else len = len1;
for(int i=0;i
if(!arr1[len1-i-1].equals(arr2[len2-i-1])) {
count ++;
}
}
return count;
}
}
第⼆题：输⼊字符串长度，字符串，计数m。从前往后计数，当数到m个元素时，m个元素出列，同时
将该元素赋值给m，然后从下⼀个数计数循环，直到所有数字都出列，给定的数全部为⼤于0的数字。输出出队队列。
例如：输⼊：len=4    str="3,1,2,4"  m=7
输出：2,3,1,4
函数原型
public String getOutString(int len, String str, int m)
[java] ：
import java.util.ArrayList;
import java.util.List;
public class HuaWeiTest {
public static void main(String[] args) {
int len=4;
String str="3,1,2,4";
HuaWeiTest hwt = new HuaWeiTest();
System.out.OutString(len, str, m));
}
public String getOutString(int len, String str, int m) { String ret ="";
String[] arr = str.split(",");
List ls = new ArrayList();
for(int i=0;i
ls.add(arr[i]);
}
for(int i=0;i
int temp = (m-1)%ls.size();
ret += ls.get(temp);
m = Integer.(temp))+temp;
}
return ret;
}
}
import java.util.ArrayList;
import java.util.List;
public class HuaWeiTest {
public static void main(String[] args) {
int len=4;
String str="3,1,2,4";

}
public String getOutString(int len, String str, int m) { String ret ="";
String[] arr = str.split(",");
List ls = new ArrayList();
ls.add(arr[i]);
}
for(int i=0;i
int temp = (m-1)%ls.size();
ret += ls.get(temp);
m = Integer.(temp))+temp;
}
return ret;
}
}
⼀．选秀节⽬打分，分为专家评委和⼤众评委，score[]数组⾥⾯存储每个评委打的分数，judge_type[]
⾥存储与score[]数组对应的评委类别，judge_type[i] == 1，表⽰专家 评委，judge_type[i] == 2，表⽰⼤众评委，n表⽰评委总数。打分规则如下：专家评委和⼤众评委的分数先分别取⼀个平均分(平均分取整)，然后，总分=专家评委平均分* 0.6 +⼤众评委* 0.4，总分取整。如果没有⼤众评委，则 总分=专家评委平均分，总分取整。函数最终返回选⼿得分。

[java] ：
public class SWTest {
public static void main(String[] args) {
int score[] = {
34,53,65,75,64
};
int judge_type[] = {
1,1,1,2,2
};
SWTest st = new SWTest();
System.out.print(st.cal_score(score, judge_type, 5));
}
int cal_score(int score[], int judge_type[], int n){
int totalExpert = 0;
int totalPublic = 0;
int numExpert = 0;
int numPublic = 0;
for(int i=0;i
if(judge_type[i]==1) {
totalExpert += score[i];
numExpert ++;
}
if(judge_type[i] == 2){
totalPublic += score[i];
numPublic ++;
}
}
if(0==numPublic){
return (int)totalExpert/numExpert;
