Daily Algorithms

Meet Coding Interview Mastery — a focused, daily practice app that turns 66 essential problems into a clear, motivating journey. Commit once, and each day unlocks exactly one carefully sequenced problem so learning compounds without overwhelm. Daily reminders at 9AM keep the streak alive, while elegant visuals and gradients make study time something to look forward to.

What makes it different?

Daily cadence: one problem per day across Arrays, Stacks, Sliding Window, Binary Search, Linked Lists, Heaps, Greedy, Hash Maps, Intervals, Graphs/BFS-DFS, Trees, DP, Tries, and Design.

Smart scaffolding: three collapsible hints to nudge the right idea at the right time; view the algorithm only after all hints; then reveal solutions when ready.

Multi-language solutions: Java, Kotlin, JavaScript, TypeScript, Python, C++, Go, and Swift — pick a preferred language and switch anytime.

Progress that sticks: SwiftData stores streaks, completion, and notes locally; build a personal knowledge base as you learn.

Beautiful, focused UI: modern gradients, subtle animations, haptics, and clean typography reduce friction and improve focus.

Personalization: add a name for a more encouraging experience and notification tone.

What you’ll master

Core patterns: two pointers, sliding window, monotonic stack, binary search variants, greedy proofs, prefix/suffix sums, hashing, intervals, topological sort, shortest paths, tree DP, memoization, and trie/backtracking.

Interview fluency: problem-to-pattern matching, trade‑off analysis, time/space complexity, and structured solution communication.

How it works

Commit from day zero — your plan begins.

Each morning at 9AM, get a gentle reminder.

Open the daily problem, reveal hints only as needed, and try first before peeking at the algorithm or solution.

Capture insights in your notes and track progress automatically.

At the finish line, get a nudge to apply — because the best time to move is now.

Why it matters
Interview success is consistency over intensity. With one high‑quality problem per day and a structure that encourages original thinking, you’ll build pattern memory, confidence, and execution speed — without burnout.

Accessibility & privacy
