Dear coders let me first tell you about my programming skills
(1) I can code in C & C++(i mean basic are clear but sometime i get stuck in arrays,strings & structures also i have very little knowledge about classes etc(i.e. OOP Concepts)).
(2) I know some basic algorithm techniques like Linear search,Binary search,Some basic sorting algorithms and a bit about Dynamic Programming & Graph Theory.
And now i want advice from you all about how should i prepare for ZCO, links to some websites will also be useful and welcomed.
