//write your code here
Scanner sc = new Scanner(System.in);
int T = sc.nextInt();
// For each Iteration I am adding the total no. of
// 1's place digits, 10's place digits, 100's place digits, and so on.
for(int i=0;i<T;i++){
int Num = sc.nextInt();
int count = 0;
for(int j=1;j<=Num;j*=10){
count += Num-j+1;
}
System.out.println(count);
}
}
}
输入：3.1001000000000222222222
我看到的输出：1922989543071888888896
期望输出：19288888888991888888896

我只需要将count变量从int更改为long。
