If you are strong enough in Data Structures, you can
 evaluate the quality of a program
(Analysis of Algorithms: running time and memory space )
 write fast programs with less memory usage
 solve new problems efficiently by choosing appropriate data
structures and algorithms
 Most importantly through this course you would be solving more
number of interview questions on data structures after each topic.
Importance of Data Structures
ALGORITHM CLASSS

To find in you…
 How smart you are to pick the appropriate data structure for a given
problem
 How strong you are on programming basics (DS)
 How good you are to decompose problems
 How quick you are to find solutions with a better logic
 To test your programming skills
… etc.
Why interviewer concentrates more on DS
