Kadane algorithm is the fastest and optimized algorithm of Maximum Sum Subarray problem. Maximum sum subarray is the contiguous subarray within a given one dimension array with the largest sum. This problem is one of the classical interview questions in IT companies like Google, Apple, Amazon, LinkedIn, Facebook, Microsoft, Uber, and many more. For example, for an array, a = [-2, -4, 4, -2, -1, 1, 5, -7] A contiguous… Read More »Kadane algorithm for Maximum sum subarray problem: Java, Python and C++ code of Kadane algorithm

Data types in NumPy NumPy supports a wide variety of data types. It is given using an attribute dtype which is a short form of data type. Most of the array creator/initializer function needs this arguments. Althoug optional, it helps numpy to determine the type of data type that array will store. Use of dtype NumPy Some time it is beneficial to use smaller data type to save memory and… Read More »Dtype NumPy: List of Data Types in NumPy and its Ranges
