The register width of a processor determines the range of values that can be represented in its registers. Though the vast majority of computers can perform multiple-precision arithmetic on operands in memory, allowing numbers to be arbitrarily long and overflow to be avoided, the register width limits the sizes of numbers that can be operated on (e.g., added or subtracted) using a single ...
LeetCode LLC, doing business as LeetCode, is an online platform for coding interview preparation. The platform provides coding and algorithmic problems intended for users to practice coding . [ 1 ] LeetCode has gained popularity among job seekers in the software industry and coding enthusiasts as a resource for technical interviews and coding ...
LEDA's integer type offers an improvement over the built-in int datatype by eliminating the problem of overflow at the cost of unbounded memory usage for increasingly large numbers. It follows that LEDA's rational type has the same resistance to overflow because it is based directly on the mathematical definition of rational as the quotient of ...
Different from other online judges, source code is not necessary to submit solutions. Instead, each problem just requires a numerical answer (which is normally too large to guess or calculate by hand), allowing users to use any methods they see fit for solving the problems, including whether or not to choose a programming language.
Raynal demonstrates how to implement an R/W lock using two mutexes and a single integer counter. The counter, b, tracks the number of blocking readers. One mutex, r, protects b and is only used by readers; the other, g (for "global") ensures mutual exclusion of writers. This requires that a mutex acquired by one thread can be released by another.
Starting with Ruby version 1.9.2 (released on 18 August 2010), the bug with year 2038 is fixed, [16] by storing time in a signed 64-bit integer on systems with 32-bit time_t. [ 17 ] Starting with NetBSD version 6.0 (released in October 2012), the NetBSD operating system uses a 64-bit time_t for both 32-bit and 64-bit architectures.
An integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers.In many settings the term refers to integer linear programming (ILP), in which the objective function and the constraints (other than the integer constraints) are linear.
Reverse mathematics is a program in mathematical logic that seeks to determine which axioms are required to prove theorems of mathematics. Its defining method can briefly be described as "going backwards from the theorems to the axioms ", in contrast to the ordinary mathematical practice of deriving theorems from axioms.
