list methods

Similar to strings, lists also have many utility methods. Yet, if string methods don’t modify the initial string and return a new one, list methods make changes to the initial list itself.

Method	Description	Examples	Results	Alternative
`count(x)`	Count the number of occurrences of `x`	`l.count(0)`	3	-
`clear()`	Make the list empty	`l.clear()`	-	`l = [] del l[:] l *= 0`
`copy()`	Copy and return the list	`new = l.copy()`	-	`new = l[:] new = list(l) new = copy.copy(l)`
`index(x)`	Find the first occurrence of `x` (`ValueError` if not in the list)	`l.index(0)`	5	-
`insert(pos, x)`	Insert `x` at position `pos`	`l.insert(1, 7)`	`[1, 7, 1]`	`l = l[:pos] + [x] + l[pos:]`
`remove(x)`	Remove `x` from the list (`ValueError` if not in the list)	`l.remove(7)`	`[1, 1]`	-
`reverse()`	Reverse the list	`l.reverse()`	-	`l = l[::-1]`
`sort()`	Sort the list in increasing order	`l.sort()`	-	`l = sorted(l)`

Again, most of the names are very intuitive. Yet, it’s not mandatory to remember them all. A quick googling will give you the needed results. These examples are for demonstration purposes. To show what is possible with Python lists.

Challenge

Given n numbers, you are asked to sort them in ascending order and print them in the output.

The first line of the input contains a single number n. The next n lines contain integers each on a separate line.

The program should output all the numbers on a single line in increasing order separated by a space.

Input	Output
5 1 4 3 0 -1	-1 0 1 3 4
