I didn’t understand any thing taught by sir , also didn’t understand clearly what exactly is the question .I have read in CodeForces also but I didn’t get any clear understanding.
plz plz help and explain in simple words (question +answer) both.

@Bhawna hey let me check this video I will explain you.

@Bhawna hey stl containers are nothing but some classes inbuilt in stl and we can use directly my making their objects ,so in this video apko type of containers btaye hue hai and har type me diff containers hai ,ye sare age wale topics me ek ek krke elaborate kie jayenge so don’t worry just remember ki kya hota hai stl containers and their type.
