Python:
def f(n):
digits = [int(i) for i in str(n)]
# 1
first_sum = digits[0] + digits[1]
# 2
second_sum = digits[1] + digits[2]
# 3
third_sum = digits[2] + digits[3]
# 4
amounts = [first_sum, second_sum, third_sum]
del amounts[amounts.index(min(amounts))]
# 5
amounts.sort()
return int(str(amounts[0]) + str(amounts[1]))
numbers = []
for x in range(1000, 10000):
if f(x) == 1318:
numbers.append(x)
print(numbers[0], numbers[-1])
import math
a = [float(input("Input x: ")), float(input("Input y: "))]
print(a)
x = a[0]
y = a[1]
y1 = x-1
if abs(x)<=1:
y2 = math.sqrt(1-x**2)
if x>=0 and y>=y1 and y<=1:
print("Yes")
elif x>=0 and x<=1 and y<y1 and abs(y)<=y2:
print("Yes")
else:
print("No")

if abs(x)<=1:

if abs(x)<=1 and abs(y)<=y2:
print("Yes")
