Next, let's again consider the three sums to be implemented:
<math>sumnum = {\sum\nolimits_{d = 1}^D {\left[ {\left( {{h_{d,i}} - \overline {{h_i}} } \right)\left( {{t_{d,j}} - \overline {{t_j}} } \right)} \right]} }</math> <math>sumdem1 = \sum\nolimits_{d = 1}^D {{{\left( {{h_{d,i}} - \overline {{h_i}} } \right)}^2}}</math> <math>sumdem2 = \sum\nolimits_{d = 1}^D {{{\left( {{t_{d,j}} - \overline {{t_j}} } \right)}^2}}</math>
Note there is some common terms in all three of these, along with a common summation index. We can thus implement them as follows:
<pre>cpaoutput[kguess] = sumnum / np.sqrt( sumden1 * sumden2 )</pre>
<pre>import numpy as np
Best Key Guess:
2b 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 </pre>
