What is the difference between clear() and fill()
I was trying to solve 1529C - Parsa's Humongous Tree.
i used the below code which gave memory limit exceeded.
then i used fill() instead of clear() function which was also used in the tutorials. And i got my soln ac.
I used clear() in first code whereas fill() in the later one. WHAT IS THE DIFFERENCE BETWEEN THOSE TWO??
