Data structures and algorithms

Data Structure : There is a relationship between the two;

algorithm : A description of the steps of the problem solving, represented in the computer as some column instructions and operations

algorithm Five features : input (input parameters), output (results obtained), certainty (step is meaningful without ambiguity), feasibility (each step is feasible) correctness (in addition to the previous features, it also has the need to reflect the problem and get the correct answer)

Algorithm efficiency metrics:

After the calculation: test methods and algorithms to one-to-one;

Pre-estimate: Time complexity (number of executions), spatial complexity
