The eight queens puzzle is a special case of the more general n queens problem of placing n non-attacking queens on an n×n chessboard. Solutions exist for all natural numbers n with the exception of n = 2 and n = 3.
(n)Code (n)Code Solutions, a subsidiary of GNFC, produces digital certificates for the Government of India (including the digital Aadhaar card for over 1 billion Indians). The solution was the result of a partnership with Entrust .
K < N. This case yields either infinitely many solutions or no solution, the latter occurring as in the previous sub-case. Example with infinitely many solutions: 3x + 3y = 3, 2x + 2y = 2, x + y = 1. Example with no solution: 3x + 3y + 3z = 3, 2x + 2y + 2z = 2, x + y + z = 1, x + y + z = 4.
Definition and parameters. A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space where is the finite field with q elements. Such a code is called a q -ary code. If q = 2 or q = 3, the code is described as a binary code, or a ternary code respectively. The vectors in C are called codewords.
Let Q be the 9x9 Sudoku matrix, N = {1, 2, 3, 4, 5, 6, 7, 8, 9}, and X represent a generic row, column, or block. N supplies symbols for filling Q as well as the index set for the 9 elements of any X. The given elements q in Q represent a univalent relation from Q to N. The solution R is a total relation and hence a function.
In computing, telecommunication, information theory, and coding theory, forward error correction ( FEC) or channel coding [1] [2] [3] is a technique used for controlling errors in data transmission over unreliable or noisy communication channels .
If a + k ≡ b + k (mod m), where k is any integer, then a ≡ b (mod m). If k a ≡ k b (mod m) and k is coprime with m, then a ≡ b (mod m). If k a ≡ k b (mod k m) and k ≠ 0, then a ≡ b (mod m). The last rule can be used to move modular arithmetic into division. If b divides a, then (a/b) mod m = (a mod b m) / b .

Nitrogen forms nine molecular oxides, some of which were the first gases to be identified: N 2 O (nitrous oxide), NO (nitric oxide), N 2 O 3 (dinitrogen trioxide), NO 2 (nitrogen dioxide), N 2 O 4 (dinitrogen tetroxide), N 2 O 5 (dinitrogen pentoxide), N 4 O (nitrosylazide), and N(NO 2) 3 (trinitramide).
