Magic Energy Calculation

In this problem, you are given five parameters related to a magical event in the game "Didiwei". The parameters are:

• type: the energy type.
• A: the attack value of the initiator.
• B: the magic power of the initiator.
• C: the physical resistance of the receiver.
• D: the magic resistance of the receiver.

The energy value is computed as follows:

• If \( type = 0 \), then the energy is \( A+B \).
• If \( type = 1 \), then the energy is \( \max(A-C,0)+\max(B-D,0) \).

Here, \( \max(x,y) \) denotes the maximum of \( x \) and \( y \). Given the five parameters, calculate the magic energy.

inputFormat

The input consists of a single line containing five space-separated integers:

• type \( (0 \text{ or } 1) \)
• A (initiator's attack)
• B (initiator's magic power)
• C (receiver's physical resistance)
• D (receiver's magic resistance)

outputFormat

Output a single integer representing the computed energy value.
