得分: 0
尝试：
// 要打印多少行
for (int i = 4; i > 0; i--) {
// 在该行中要打印多少个'#'
for (int j = 0; j < 2 * i - 1; j++) {
System.out.print("#");
}
// 到下一行
System.out.print("\n");
}
英文:
Try:
// How many lines to print
for (int i = 4; i > 0; i--) {
// How many '#' to print in that line
for (int j = 0; j < 2 * i - 1; j++) {
System.out.print("#");
}
// To next line
System.out.print("\n");
}
