Diabetes

You really love sweets and come across a sweet shop that has $N$ sweets in a row, and each of them has some cost(not necessarily the same). You have $M$ rupees and are looking to buy as many as you can. You can start at any sweet and start buying sweets linearly, that is, if you buy the $i$th sweet, the next sweet you buy has to be $(i+1)$th. You can only buy sweets as long as you can afford them
