* add zig examples
* improved zig binary search
This commit improves the binary search code in zig. The function has
been made generic and the logic has been cleaned up a bit.
The code has been updated to work with zig versions >= 0.9
* simplify zig selection sort
This commit simplifies the logic of the zig selection sort. It now swaps
in place the elements of the array instead of creating another array.
This avoids allocating heap memory.
The code has also been upgraded to zig version 0.9.1
* make zig recursion examples generic
This commit modifies the zig examples for the recursion chapter to be
generic. It also updates the code to zig version 0.9.1
* update chapter 4 examples
This commit updates the zig examples in chapter 4. In particular
examples have been made generic where possible. The code has been
updated to zig version 0.9.1
* update zig hash table examples
This commit updates the examples for the chapter 5 about hash tables.
Some improvements have been done (using a set instead of a map). The
code has been updated to zig version 0.9.1
* update breadth first search zig example
This commit updates the zig example for the breadth first search
algorithm. It adds a unit test and updates the code to zig version 0.9.1
* revamp zig dijkstra example
* add comments in dijkstra zig
* fix zig greedy algorithm
* add test for zig dijkstra
* add test for zig greedy algorithm
* improve zig chapter 9 exercise
This commit improves the zig exercise to comput the longest common
subsequence.
A main function has been added and the allocator code has been extracted
from the `subsequence` function.
* The original code did not consider the exit condition when the stations cannot perfectly cover the states_needed.
* The code in 09_dynamic_programming/python/01_longest_common_subsequence.py is completed. And the 02_longest_common_substring.py is added.
