}2. JAVA SpringBootYou may have precision problems, but you can use BigDecimal optimization @RestController
@RequestMapping("/sliderCaptcha")
public class SliderCaptchaController {
@PostMapping("/isVerify")
public boolean isVerify(List<Integer> datas) {
int sum = 0;
for (Integer data : datas) {
sum += data;
}
double avg = sum * 1.0 / datas.size();
double sum2 = 0.0;
for (Integer data : datas) {
sum2 += Math.pow(data - avg, 2);
}
double stddev = sum2 / datas.size();
return stddev != 0;
