A progress bar is an element of graphical interface that displays the progress of a process for this very moment before it is completed. Let’s take a look at the following form of such a bar.
A bar is represented as n squares, located in line. To add clarity, let’s number them with positive integers from 1 to n from the left to the right. Each square has saturation (ai for the i-th square), which is measured by an integer from 0 to k. When the bar for some i (1 ≤ i ≤ n) is displayed, squares 1, 2, … , i - 1 has the saturation k, squares i + 1, i + 2, … , n has the saturation 0, and the saturation of the square i can have any value from 0 to k.
So some first squares of the progress bar always have the saturation k. Some last squares always have the saturation 0. And there is no more than one square that has the saturation different from 0 and k.
The degree of the process’s completion is measured in percents. Let the process be t% completed. Then the following inequation is fulfilled:
An example of such a bar can be seen on the picture.
For the given n, k, t determine the measures of saturation for all the squares ai of the progress bar.
string[] first = Console.ReadLine().Split(' '); //split by space
int n = int.Parse(first[0]);
int k = int.Parse(first[1]);
int t = int.Parse(first[2]);
int res = n*k*t/100;
int full = res/k;
int left = res%k;
int[]resArr = new int[n];
for(int i=0; i<n; i++){
resArr[i] = i<full ? k : (i==full ? left : 0);
}
Console.WriteLine(String.Join(" ", resArr));
利用了 C# 以及Java 整數計算會自動捨去的原理,就不需要math.floor去取得整數了
然後使用了一個簡單的三元不等式去對答案的陣列進行填充。
Java解決方案
方案1
import java.util.Scanner;
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String[] first = scanner.nextLine().split(" ");
int n = Integer.parseInt(first[0]);
int k = Integer.parseInt(first[1]);
int t = Integer.parseInt(first[2]);
int res = n*k*t/100;
int full = res/k;
int left = res%k;
int[]resArr = new int[n];
for(int i=0; i<n; i++){
resArr[i] = i<full ? k : (i==full ? left : 0);
}
System.out.println(String.join(" ", Arrays.stream(resArr).mapToObj(String::valueOf).toArray(String[]::new)));
