How to learn step by step to be a good programmer !!!

Revision en3, by asifthegreat, 2017-08-25 21:16:25

Hello everybody , how are you ? Today I am going to describe some contents (programming) Which can be helpful for contestants.

At first I assume that you all know about C/C++ language . But It doesn't matter . I think you also know about conditional logic , loop , datatype(input/output) , strings, array, function , basic bitwise operation etc . I think then you should learn lots of Mathematical terms such as :

Prime number , GCD , LCM , Eular's Totirnt Function , Bigmod , Modular inverse , Extended GCD , combinatorics, permutation , combination , inclusion exclusion principle ,probability , Expected value , Base conversation , Big integer , cycle , Gawssian elimination etc etc........

Then.....

you have to learn about sorting and searching . like : Insertion sort , bubble sort , merge sort , selection sort , merge sort , county sort etc . NOTE : THERE IS A THING NAMED "qsort" function is C language.....don't use it . There is an algorithm named "anti-qsort" . If you use it in codeforces , anyone can easily hack your solution because anti-qsort algorithm generates worst case for qsort and in the worst case , it's time complexity will be O(n^2) . But you can use Standerd Template Library .

Then........

You have to learn Binary search , Backtraking , ternary search etc...

Then.......

you have a task to learn lots of data structures . Such as : Linked list , Stack,Queue,heap , vector,graph,tree,segment tree , binary search tree , sqare root segmentation , disjoint set union , Lazy with proposition , lazy without proposition , Binary indexed tree , map , set , pair etc etc....

Then........

You haVe to learn greedy technique , Dyanamic programming , Graph algorithm , Flow , Adhoc , Geometry etc etc , I have summarized the contents bellow : 1. Dynamic Programming 2. Greedy 3 .Complete Search 4 . Flood Fill 5 . Shortest Path 6 . Recursive Search Techniques 7 . Minimum Spanning Tree 8 . Knapsack 9 . Computational Geometry 10 .Network Flow 11 . Eulerian Path 12 . Two-Dimensional Convex Hull 13 . BigNums 14 . Heuristic Search 15 . Approximate Search 16 . Ad Hoc Problems

If you clearup all those above , you will find a great programmer inside you , but mind it , It is not an easy tusk....You have to practice a lot . If you don't practice , you will never be able to be a good programmer .....!!!

SO , NO MORE TODAY ,,,, STAY WELL EVERYBODY,,,,ALWAYS TRY TO HELP OTHERS...HAPPY CODING !
