## Problem: Pipes in Pool

A pool with volume V fills up with two pipes. Each pipe has a certain flow rate (the liters of water, flowing through a pipe for an hour). The worker starts the pipes simultaneously and goes out for N hours. Write a program that finds the state of the pool the moment the worker comes back.

### Input Data

Four lines are read from the console:

• The first line contains a number V – the volume of the pool in liters – an integer in the range of [1 … 10000].
• The second line contains a number P1 – the flow rate of the first pipe for an hour – an integer in the range of [1 … 5000].
• The third line contains a number P2 – the flow rate of the second pipe for an hour – an integer in the range of [1 … 5000].
• The fourth line contains a number H – the hours that the worker is absent – a floating-point number in the range of [1.0 … 24.00].

### Output Data

Print on the console one of the two possible states:

• To what extent the pool has filled up and how many percent each pipe has contributed with. All percents must be formatted to an integer (without rounding).
• "The pool is [x]% full. Pipe 1: [y]%. Pipe 2: [z]%."
• If the pool has overflown - with how many liters it has overflown for the given time - a floating-point number.
• "For [x] hours the pool overflows with [y] liters."

Have in mind that due to the rounding to an integer, there is data loss and it is normal the sum of the percents to be 99%, not 100%.
