    It is a 5% rated problem, indicating it is one of the easiest on the site. The initial approach a beginner can come up with is a bruteforce attempt. Given the upper bound of 1000 in this case, a bruteforce is easily achievable for most current home computers. A Python code that solves it is presented below.

    A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. [11]

    en.wikipedia.org/wiki/Extreme_programming

    Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, [1] [2] [3] it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted.

    These are of little concern in practice, being sufficiently rare that they are unnecessary to avoid explicitly when generating keys randomly. A simple fix was proposed: XORing each subkey with a 16-bit constant, such as 0x0DAE. [8] [9] Larger classes of weak keys were found in 2002. [10]

  7. Byzantine fault - Wikipedia

    en.wikipedia.org/wiki/Byzantine_fault

    The problem of obtaining Byzantine consensus was conceived and formalized by Robert Shostak, who dubbed it the interactive consistency problem. This work was done in 1978 in the context of the NASA-sponsored SIFT [5] project in the Computer Science Lab at SRI International. SIFT (for Software Implemented Fault Tolerance) was the brainchild of ...

    General Problem Solver (GPS) is a computer program created in 1957 by Herbert A. Simon, J. C. Shaw, and Allen Newell (RAND Corporation) intended to work as a universal problem solver machine. In contrast to the former Logic Theorist project, the GPS works with means–ends analysis .

    The Bangalore and California-based company raised $4.5 million in a Series A [12] round funding led by DHI Group Inc. with participation from Prime Ventures and Beenext in February 2017. [4] In December 2018, HackerEarth secured the next round of funding. The Jo Hirao Office led the Series B funding for a total value of $6.5 million.
