The problem is missing a critical edge case. For the input: nums = [10,10,9,0], k = 1, limit = 20 the expected answer is 0 because the subsequence [0] has an alternating sum of 0 and product 0 ≤ limit ...

Abstract: As a class of exact Bayesian filtering algorithms for non-linear/non-Gaussian recursive estimation of dynamic stochastic systems which can randomly switch on and off, the Bernoulli filter ...
