What is the Base Case in DP?
Updated Apr 28, 2026
Short answer
The simplest subproblem where the answer is known without further calculation.
Deep explanation
Dynamic Programming (DP) is an algorithmic paradigm that solves a given complex problem by breaking it into subproblems and stores the results of subproblems to avoid computing the same results again. The simplest subproblem where the answer is known without further calculation.
Real-world example
Cashiers giving change using the minimum number of coins.
Common mistakes
