# Remove the last value from the app.reds list and store it in newVal.

### Fix Your Code Here ###

newVal $=0$

# Creates a new list with the last value.

newList $=[$ newVal $]$

# Add all of the other red values to the newList.

### $($HINT: Loop over app.reds and add each element to newList.$)$

### Place Your Code Here ###

# Sets app.reds equal to the new list.

app.reds $=$ newList

# Shifts where the next rectangle will be drawn.

app.y $+=25$
