Question

A non-empty array A consisting of N numeric values is
given.
The product of quadruplet (P, Q, R, S) equates to A[P]
A[Q] * A[R] * A[S]
(0 SP<Q <R<S<N).
For example, array A such that:
A[2] = 2
A[3] = -2
A[4] = 5
A[0] = -3
A[5] = 6
A[1] = 1
A[6] = 1
• (0, 1, 2, 3), product is -3*1*2*-2 = 12
• (1, 2, 4, 5), product is 1 * 2*5*6 = 30
(2, 4, 5, 6), product is 2 * 5 * 6* 1 = 60
60 is the product of quadruplets (2, 4, 5, 1), which is
maximal.​
