题目标题： 用m个连续奇数之和表示m的立方 题目描述：

public static String cubeOfInteger(int num){
    String str = "";  int result = num * num * num;  int count = 0;  if(num % 2 == 0){ int count1 = (num * num + 2) / 2;  count = count1 - num / 2;  for(int i = count; i < num + count; i++){ if(i == num + count - 1){
                str =str + (2 * i - 1);  }else {
                str = str + (2 * i - 1) + "+";  }
        }
    } if(num % 2 == 1){ int count1 = (num * num + 1) / 2;  count = count1 - num / 2;  for(int i = count; i < num + count; i++){ if(i == num + count - 1){
                str =str + (2 * i - 1);  }else {
                str = str + (2 * i - 1) + "+";  }
        }
    } return str; }

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

int num = input.nextInt(); System.out.println(cubeOfInteger(num));
}
