package com.zeph.j2se.alg;
public class Heart {
int HighLevel(int wide) {
int i = 0, j = 0, k = 0, t = 0, m = 0, n = 0, count = 1;// i控制循环内高度，j控制每行前面空格，k控制输出的*数
// t控制高层星号中间空格，m记录高层最底行的星数，以下逐行增4
// n记录顶行空个数，以下逐行减4；count记录高层高度，与high无关
m = (wide - 4) / 2;
do {
count++;
m -= 4;
} while (m > 4);
if ((wide - 4) % 2 == 0)// 区别对待奇偶宽度，奇数中间最小空1个，偶数最小空两个
{
n = 2 + 4 * (count - 1);
m--;
} else
n = 1 + 4 * (count - 1);
for (i = 0; i < count; i++) {
for (j = (count - i) * 2; j > 0; j--)
System.out.print(" ");
for (k = 0; k < m; k++)

System.out.print("\n");
}
return 0;
}
int LowLevel(int wide) {
int i = 0, j = 0, k = 0;// i控制输出行，j控制输出每行前的空格，k控制输出*
int high = 0, tmp = wide;
do// 计算所需高度

public static void main(String[] args) {
int wide = 30;
Heart heart = new Heart();
heart.HighLevel(wide);
heart.LowLevel(wide);
}
