C ++中的超级战俘
让我们看下面的实现以更好地理解-
#include <bits/stdc++.h>
using namespace std;
typedef long long int lli;
class Solution {
public:
int powerMod(lli base, lli power){
lli mod = 1337;
lli ret = 1;
while(power){
if(power & 1) ret = (ret * base) % mod;
base = (base * base) % mod;
power >>= 1;
}
return ret;
}
int superPow(int a, vector<int>& b) {
if(b.size() == 0) return 1;
int last = b.back();
b.pop_back();
return (powerMod(superPow(a, b), 10) * powerMod(a, last)) % 1337;
}
};
main(){
Solution ob;
vector<int> v = {1,0};
cout << (ob.superPow(2, v));
}输入值
2 [1,0]
输出结果
