```c
#include <stdio.h>
int main() {
unsigned int a, b, c;
scanf("%d %d %d", &a, &b, &c);
if (a + b <= c || a + c <= b || b + c <= a) {//这里错力把"b + a <= c"改为"b + c <= a"
printf("Not triangle\n");
}
else {
int t = 0; if (a > b) {
t = b;
b = a;
a = t;
}
if (a > c) {
t = c;
c = a;
a = t;
}if (b > c) {
t = c;
c = b;
b = t;
}if (a * a + b * b > c * c) { printf("Acute triangle\n"); }
else if (a * a + b * b < c * c) {
printf("Obtuse triangle\n");
}
else if (a * a + b * b == c * c) { printf("Right triangle\n"); }
if (a == b || b == c || a == c) { printf("Isosceles triangle\n"); }
if (a == b && b == c) { printf("Equilateral triangle\n"); }

}
```
改好力！求关喵！
