Accenture Coding Question | Electrostatic Field | CodeWindow

Electrostatic

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:
Input 1: Integer array denoting the magnitude of each charge.
Input 2: String denoting nature of each charge ith represents a sign of charge at ithentry represents a sign of charge at ith location in input1
Input 3: No of charges it holds (length of input1)

Output Specification:
Return the next maximum electrostatic field possible in the rod.

Example 1:
Input 1: {4,3,5}
Input 2: PNP
Input 3: 3

Output: 600
Explanation:
The maximum electric charge on the rod is 4-3+5 = 6 units. So the magnitude of the electric field would be 6*100=600

Example 2:
Input 1: {2,3}
Input 2: PN
Input 3: 2

Output : 100
Explanation:
The maximum possible electric charge on the section of the rod is 2-3=-1 unit.

c=list(map(int, input().split()))
e=input()
l=int(input())
e=list(e)
#print(c)
#print(e)
count=0
for i in range(l):
    if e[i]=='P':
        count=count+c[i]
    else:
        count=count-c[i]
        
print(abs(count*100))
