data = []
print("Enter numbers:",end="")
for i in range(0, k):
num = int(input())
data.append(num)
print("Number before sorting:", data)
# sorting implementation start here
for i in range(0, data.__len__()):
for j in range(1 + i, data.__len__()):
if data[i] > data[j]:
temp = data[i]
data[i] = data[j]
data[j] = temp
print("After Sorting numbers are:", data)
```

#### Output:
