why is test 1 giving out 4

ok thx

Three 1's => 1000 points
...
One   1   =>  100 points
One   5   =>   50 point

1 1 1 5 1   1150: 1000 (for three 1s) + 50 (for the 5) + 100 (for the other 1)

Is it clear now?

the example shows this:
1 1 1 3 1 1100: 1000 (for three 1s) + 100 (for the other 1)

It's the same as the example with 1 1 1 3 1, just with a 5 instead of the 3, so 1100 + 50 = 1150. Why would it be 1100?
