201703-1 分蛋糕 Java

思路：

注意最后如果剩余蛋糕的重量小于k，也算一个人分到

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();//几块蛋糕
		int k = sc.nextInt();//要多重的蛋糕
		int cakes[] = new int[n];
		for(int i=0;i<n;i++) {
			cakes[i] = sc.nextInt();
		}
		int count = 0;
		int temp = 0;
		for(int j=0;j<n;j++) {
			temp += cakes[j];
			if(temp >= k) {
				count++;
				temp = 0;
			}
		}
		if(temp > 0) {
			count++;
		}
		System.out.println(count);
	}

}
