# Roadmap To DS Algo / Competitive Programming in 2.5 months

 -   Some basics of maths

 -   basic of language

        - variables

        - functions - pass by value and reference

        - loops

        - conditional statements

        - arrays 

        - pointer

        - bit operations

        - Time and space complexity

 -   arrays

        - Problem solving no algos only brute force

 -   searching linear , binary search

 -   sorting merge sort, quick sort, inbuilt sort function

 -   prefix sum 

 -   sliding window

 -   2d arrays

        - problem solving no algos only brute force

 -   linked list

        - problem solving algos + brute force

 -   INTRO TO STL (c++) / collections library (java / python)

        -   basic problem solving

 -   Recursion and backtracking 

        -  problem solving

 -   stack and queue

        -  problem solving

 -   trees

       - binary -> traversal

       - binary search trees

 -   n ary

       - PROBLEM SOLVING

 -   intro to heaps

 -   hash maps

## from here COMPETITIVE part also starts

 - Graphs

 - Dynamic Programming

     - rec

     - top-d

     - bottom-u

     - basically mathematical dp

 - Strings

     - basics of string library

     - basic problem solving
