The code below is for a simple vending machine. Each item in the list represents a coin. If the coins 20p, 50p and two £1 coins were added, the list would be

coins = [20,50,100,100,0,0,0,0,0,0]

Change the code below –

• change coins so it has 5 coins in it. A 50p, two 10p, a 2p and a 1p.
• change x to be the first position of the list.
• Change the while loop so the condition is less than the length of the list.
• change the last ????? so it adds one to x.

coins = [0,0,0,0,0,0,0,0,0,0]
x = ????
sum = 0
while ?????? :
    sum = sum + coins[????]
    x= ??????
print (sum)
