n,b=map(int,input().split())
h = list()
for i in range(n):
h.append(input())
h.sort(reverse=True)
sum =0
nb = 0
for j in h:
sum += int(j)
nb += 1
if sum >= b:
print(nb)
break
这样就对了
n,b=map(int,input().split())
h = []
for i in range(n):
h.append(int(input()))
h.sort(reverse=True)
dd =0
nb = 0
for j in range(n):
dd += h[j]
nb += 1
if dd >= b:
print(nb)
break
