// 	There are N elephants in the Zoo.The elephant with number K(1 ≤ K ≤ N) will be happy if he receives at least AK candies.There are C candies in all in the Zoo.

// 	The Zoo staff is interested in knowing whether it is possible to make all the N elephants happy by giving each elephant at least as many candies as he wants,
// 	that is, the Kth elephant should receive at least AK candies.Each candy can be given to only one elephant.Print Yes if it is possible and No otherwise.
