update this code so that the y axis is labelled "sensor values" and x axis is labelled "time in seconds"
}

You will implement a method for the LinkedList class named "delete48in148". That is, whenever there is a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample, Before: 1 -> 4 -> 8 LAfter: 1 Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8 After: 7 -> 1 -> 9 -> 4 -> 8 Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9 After: 7 -> 1 -> 9 Note from the above example that, after deleting one instance of 48, there may be new instances of 148 formed. You must delete ALL of them. Requirement: Your implementation must be ITERATIVE (i.e., using a loop). You must NOT use recursion. Recursive solutions will NOT be given marks. import ... # No other import is allowedarrow_forward
