A is an array and p and q indexes of the array such as you gonna sort the sub-array A[p..r]. B is a sub-array which will be populated by the sort.
A call to p-merge-sort(A,p,r,B,s) sorts elements from A[p..r] and put them in B[s..s+r-p].
p-merge-sort(A,p,r,B,s)
n = r-p+1

In following example we will create table movies with AWS Ruby SDK v2.
Here, each Movie as one unique Partition Key as id, and Range Key year. Apart from this we want to be able to query movies with their name, hence we will create a Global Secondary Index (GSI) name-year-index with name as Hash Ke...
Q-learning is a variant of model-free reinforcement learning. In Q-learning we want the agent to estimate how good a (state, action) pair is so that it can choose good actions in each state. This is done by approximating an action-value function (Q) that fits in equation below:
Where s and a are ...
