SLAE Problems for Competitive Programming [Tutorial]

Revision en1, by MazzForces, 2018-06-13 12:43:24

Hello Codeforces,

SLAE stands for system of linear equations. Basically, consider we have a set of equations of the form :

a0·x0 + a1·x1 + a2·x2 + ... + an - 1·xn = m
b0·x0 + b1·x1 + b2·x2 + .... + bn - 1·xn - 1 = n
c0·x0 + c1·x1 + c2·x2 + .... + cn - 1·xn - 1 = o
.....

Note that all

a, b, c..

are arrays belonging to

and

m, n, o..

are arbitrary numbers
