rt， 我在P4151 [WC2011] 最大XOR和路径 一题中熟练使用了如下的快读，并成功 WA。

inline int read() {
	int x = 0, f = 1; char ch = getchar();
	while (ch < '0' || ch > '9') {
		if (ch < '0' || ch > '9') 
		    f = -1;
		ch = getchar();
	}
	while (ch >= '0' && ch <= '9') x = x * 10 + ch - '0', ch = getchar();
    return x * f;
}
inline ll R() {
	ll x = 0, f = 1; char ch = getchar();
	while (ch < '0' || ch > '9') {
		if (ch < '0' || ch > '9') 
		    f = -1;
		ch = getchar();
	}
	while (ch >= '0' && ch <= '9') x = x * 10 + ch - '0', ch = getchar();
    return x * f;
}

而当我使用之前的写法:

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 * 10 + ch - '0', ch = getchar();
	return x * f;
}
inline ll R() {
	ll 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 * 10 + ch - '0', ch = getchar();
	return x * f;
}

就没有问题了。请问是我的快读挂了吗？
