you have given an array you have to maximize the cost factor of array and cost can be calculated in following way ↵
↵
COST = A*a[i]-B*a[j]+C*a[k]+D*a[l]+E*a[m] where i<j<k<l<m ↵
↵
now you have given A,B,C,D,E , maximize the cost of given array↵
↵
sample test case ↵
n= 5↵
array = { 10 17 15 6 17} ↵
A=8, B=5, C=4, D=6, E=9↵
↵
Output is 172
