It doesnt cover all the data structure and algorithms but whatever it covers, it explains them well. In an algorithm instructions can be executed any number of times, provided the instructions themselves indicate the repetition. If we stop to think about it, we realize that we interact with data structures constantly. For an array, in which partitioning leads to unbalanced subarrays, to an extent where on the left side there are no elements, with all the elements greater than the pivot, hence on the right side and if keep on getting unbalanced subarrays, then the running time is the worst case, which is on 2.
