Explain how the SWAP function works, which makes each line of this function.

Thanks in advance.

```
def sorte (num):
For i in Range (Len (NUM)):
L = I.
For k in Range (I + 1, Len (NUM)):
IF NUM [K] & LT; NUM [L]:
L = K.
SWAP (Num, L, I)
DEF swap (V, X, Y):
T = V [x]
V [x] = V [y]
V [Y] = T
LST = [2,235,654,0,434687,754,32,1]
K = max_num (LST)
Sorte (LST)
Print (K)
Print (LST)
```

## Answer 1, Authority 100%

The function takes a list V and changes the elements with indices x and y in it with places.

Right:

```
t = v [x] # save the Xth element in a temporary variable
V [x] = v [y] # write in the X-si-sip position of an array value from y-th element
v [y] = t # write to the Y-th position
# which was saved in a temporary variable
```

The most ridiculous thing is that for this it was not necessary to make a whole function, everything could be written in one line using the assignment with unpacking:

```
v [x], v [y] = v [y], v [x]
```
