用pow的我没有TLE，但是WA了（24分）？？？

这题要用高精度咩？

#include<bits/stdc++.h>
using namespace std;
#define intunsigned long long
int a,b,c;
inline int read() {
    int x=0,f=1;
    char ch=getchar();
    while(ch<'0'||ch>'9') {
        if(ch=='-')f=-1;
        ch=getchar();
    }
    while(ch>='0'&&ch<='9') {
        x=(x<<1)+(x<<3)+(ch^48);
        ch=getchar();
    }
    return x*f;
}
inline void write(int x) {
    if(x<0)putchar('-'),x=-x;
    if(x>9)write(x/10);
    putchar(x%10 +'0');
}
signed main() {
    a=read();
    b=read();
    c=read();
    write(a);
    printf("^");
    write(b);
    printf(" mod ");
    write(c);
    printf("=");
    int d=pow(a,b);
    write(d%c);
    return 0;
}
