Data Structures and Algorithms for Placements
Why colleges run this
Data structures and algorithms decide almost every technical interview; a cohort that has solved and defended tracked problems walks into placements measurably ahead.
Course outcomes
CO1
Analyse the time and space complexity of an algorithm using Big-O notation
K4CO2
Implement the core data structures — lists, stacks, queues, trees, heaps and graphs
K3CO3
Apply recursion, backtracking and dynamic programming to unfamiliar problems
K3CO4
Select an appropriate algorithmic strategy for a stated problem constraint
K4CO5
Solve and defend tracked interview problems under timed conditions
K3Modules tap a module for its theory & lab
Hours shown are the recommended 5-day format — module time scales to the duration you pick.
