Programming and DSA with Python for Placement Coding Rounds

Coding rounds at TCS, Infosys, IBM, Wipro and Cognizant test a narrower and easier range than product-company interviews, but they test it in ways that catch unprepared students. You will be asked to print a diamond pattern, write bubble sort from memory, and reverse a linked list on a whiteboard — none of which appear in standard competitive-programming preparation.
