of money M in the range 100..1,000,000. He knows how many years Y (range: 0..400) he intends to invest the money in the bank. Help him learn how much money he will have in the future by compounding the interest for each year he saves. Print an integer answer
without rounding. Answers for the test data are guaranteed to fit into a signed 32 bit integer.
输入描述
* Line 1: Three space-separated integers: R, M, and Y

提示
INPUT DETAILS:5% annual interest, 5000 money, 4 years
OUTPUT DETAILS:
Year 1: 1.05 * 5000 = 5250
Year 2: 1.05 * 5250 = 5512.5
Year 3: 1.05 * 5512.50 = 5788.125
Year 4: 1.05 * 5788.125 = 6077.53125
The integer part of 6077.53125 is 6077.

这个问题和《POJ2390 Bank Interest【水题】》是同一个问题，代码直接用就AC了。

题记：程序做多了，不定哪天遇见似曾相识的。AC的C++程序如下：
/* POJ2390 Bank Interest */
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
int r, m, y;
cin >> r >> m >> y;
cout << (int)(m * pow(1 + r / 100.0, y)) << endl;
return 0;
}
