required answer in python programming

Electrostatics Doug is fond of change, every now and then he tries to do new things. This time, he caught up with a rod comprising of negative (N) and positive (P) charges. He is asked to calculate the maximum net electrostatic field possible in the region due to the-rod. Note: Assume, Electrostatic Field = Total charge 100 Input Specification: input1: integer array denoting the magnitude of each charge input2: String denoting nature of each charge, ith entry represents a sign of charge at ith location in input1 input3: No. of charges it holds (length of input 1 ) Output Specification: Return the maximum electrostatic field possible in the rod. Example 1: input1: {4,3,5} input2: PNP input 3:3 Output: 600 Example 1: input 1:{4,3,5} input2: PNP input3: 3 Output: 600 Explanation: The maximum electric charge on the rod is 43+5=6 units, so the magnitude of the electric field would be 6100=600. Example 2: input 1:{2,3} input2: PN input 3:2 Output: 100 Explanation: The maximum possible electric charge on the section of the rod is 23=1 unit. As the magnitude is never negative so 1=1 so the magnitude of the electric field would be 1100=100. \# Read only region start class Usermaincode (object): @classmethod def findmaximum(cls, input1, input2, input3): input1 : int [] input2 : string input3 : int Expected return type : int \# Read only region end \# Write code here pass Use Custom Input
