WebbThe idea is to maintain a maximum (positive-sum) subarray “ending” at each index of the given array. This subarray is either empty (in which case its sum is zero) or consists of one more element than the maximum subarray ending at the previous index. The algorithm can be implemented as follows in C++, Java, and Python: WebbThe numpy.log () is a mathematical function that is used to calculate the natural logarithm of x (x belongs to all the input array elements). It is the inverse of the exponential function as well as an element-wise natural logarithm. The natural logarithm log is the reverse of the exponential function, so that log (exp (x))=x. something just like this nba
