寒假15：算法训练 接水问题

代码，通过了100%的数据：

import java.util.Scanner;public class 接水问题 {	public static void main(String[] args) {				Scanner sc=new Scanner(System.in);		int n=sc.nextInt();		int m=sc.nextInt();				int[] data=new int[n];		int[] shui=new int[m];				for (int i = 0; i < data.length; i++) {			data[i]=sc.nextInt();			if(i<m)				shui[i]=data[i];		}		int count=0;		while(getBool(shui)){			int min=getMin(shui);			count+=min;			for (int i = 0; i < shui.length; i++) {				shui[i]-=min;				if(shui[i]==0&&m<data.length)					shui[i]=data[m++];			}		}		System.out.PRintln(count);	}	private static int getMin(int[] shui) {		int k=100*100;		for (int i = 0; i < shui.length; i++) {			if(k>shui[i]&&shui[i]>0)				k=shui[i];		}		return k;	}	private static boolean getBool(int[] shui) {		for (int i = 0; i < shui.length; i++) {			if(shui[i]>0)				return true;		}		return false;	}}
