MLE and MOM for piecewise uniform

Let 0.2,1.2,1.4,0.3,0.9,0.70.2, 1.2, 1.4, 0.3, 0.9, 0.7 be the observed values of a random sample of size 66 from a continuous distribution with the probability density function f(x)={1,0<x≤12 12θ−1,12<x≤θ 0,otherwise,f(x)=\begin{cases} 1, & 0 < x \le \frac{1}{2} \ \frac{1}{2\theta-1}, & \frac{1}{2} < x \le \theta \ 0, & \text{otherwise,} \end{cases} where θ>12\theta > \frac{1}{2} is unknown. Then the maximum likelihood estimate and the method of moments estimate of θ\theta, respectively, are
