#1)
print(sum(x**2 for x in range(1,101)))
#Ответ:338350

#2)
#Ответ: [0, 8, 16, 24, 32]


#3)
count = 0
print(sum([count + 1 for x in range(20) if x % 2 == 0]))
#Ответ: 10

#4)
b = [64, 8, 72, 1, 56,78, 7, 59, 9, 80]
print(sum([0 + 1 for x in b[::2] if x % 2 == 0]))
#Ответ: 3

#5)

print(len([x for x in range(1,1000) if x % 7 == 0 or x % 11 == 0]))
#Ответ: 220
