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)
