Goal

Don't be fail in coding test anymore in 2020.

• Algorithm

  theory : summarized by mark down.

  problems : problem solved by c++.

• Problem solving

  Solve bunch of algorithm problems.

Self diagnosis!

Do diagnosis what my problem is then, solve again later.

• simulation

  1. Array_rotation : 배열을 회전하는 과정에서 index (i,j) 뒤바뀌는 것이 어렵다.

  • Iterator loop : [Kakao]broadcast_live, [Kakako]candidate_key
  • Map data structure : [Kakako]chat_room
  • Combination set based on DFS : The spring's test i couldn't solve : 17142_lab3[Samsung]
15684_ladder_control[Samsung], 15686_chicken_delivery[Samsung]
  • String : [Kakao]match_score
  • Bit operation : [Kakako]candidate_key, [Bit masking]1194_moon
