提出

code: python

a, b, c = map(int, input().split())

if (4 * a * b < pow(c, 2) + pow(a, 2) + pow(b, 2) + 2 * a * b - 2 * a * c - 2 * b * c):

print("Yes")

else:

print("No")

解答

code: python

a, b, c = map(int, input().split())

if (c - a - b <= 0):

print('No')

elif (4 * a * b < (c - a - b) ** 2):

print('Yes')

else:

print('No')

code: python

a, b, c = list(map(int, input().split()))

# a + 2√ab + b < c

# 2√ab < c - a -b

# 4ab < (c-a-b)^2

if 4 * a * b < (c-a-b)**2:

print("Yes")

else:

print("No")
