I've been doing competitive programming for about 2-3 months and have gone through these topics so far:

• Basics (Conditional statements, loops, switch)
• Bitwise operators
• Arrays, Strings
• Greedy algorithms
• Linear search, Two pointers
• Binary search
• Prefix sum
• Sorting
• Number Theory (sieve, modulo, exponentiation)
• Pointers
• STL
• Recursion
• Basic Probability and Combinatorics

Lately, I've been practicing questions in the 1000-1400 range.

Next, I'm thinking of diving into:

• Stack

• Queue

• Tree

• Heap

• Hashmap

• Trie

• Backtracking

• Graph (BFS, DFS, Shortest Path)

• Dynamic Programming

Does this sequence seem okay? Any tips on how to approach these topics?
