2015  machine test-what is the highest score, and 2015  machine's highest score

Description:

The teacher wants to know the highest score from xx to xx.
Now, ask the simulation instructor. Of course, teachers sometimes need to update their scores.
 
Question category: Sorting
Difficulty: elementary
Running time limit: Unlimited
Memory limit: Unlimited
Stage: Pre-Employment exercises
Input:
The input contains multiple groups of test data.
The first row of each group is two positive integers N and M (0 <N <= 5000, 0 <M <). The sub-table represents the number of students and the number of operations.
Student ID numbers are numbered from 1 to N.
The second row contains N integers, indicating the initial score of the N students. The number of I represents the score of the students whose ID is I.
Next there are M rows. Each line has A character C (only 'q' or 'U'), and two positive integers A and B.
When C is 'Q', it indicates that this is A query operation. It asks the students whose ID ranges from A to B (including A and B) about the highest score.
When C is 'U', it indicates that this is an update operation. You must change the score of students whose ID is A to B.

Output:
Output the highest score in one row for each query operation.
 
Sample input:
5 6
1 2 3 4 5
Q 1 5
U 3 6
Q 3 4
Q 4 5
U 2 9
Q 1 5

Sample output:
5
6
5
9

The Code is as follows:

Public class zui_GaoFen {public static void main (String [] args) {consumer SC = new consumer (System. in); // initialization data N: Student count M: Operation count String firstLine = SC. nextLine (); String [] initalNums = firstLine. split (""); int N = Integer. parseInt (initalNums [0]); int M = Integer. parseInt (initalNums [1]); // initialize the result String secondLine = SC. nextLine (); int [] scores = new int [N]; scores = getScores (secondLine); // command int [] Max = new int [M]; int count = 0; for (int I = 0; I <M; I ++) {String q_or_u = SC. next (); if (q_or_u.equals ("Q") {int a = SC. nextInt (); int B = SC. nextInt (); Max [count] = getMax (scores, A-1); count ++;} if (q_or_u.equals ("U") {int a = SC. nextInt (); int B = SC. nextInt (); scores [A-1] = B;} for (int I = 0; I <count; I ++) {System. out. println (Max [I]);} SC. close ();} public static int getMax (int [] score, int a, int B) {int temp = score [a]; for (int I =; I <= B; I ++) {if (score [I]> temp) {temp = score [I] ;}} return temp ;} public static int [] getScores (String secondLine) {String [] scores = secondLine. split (""); int [] res = new int [scores. length]; for (int I = 0; I <scores. length; I ++) {res [I] = Integer. parseInt (scores [I]);} return res ;}}
