Asked in companies
You are given an n×n chessboard. Rows and columns of the board are numbered from 0 to ‘n’-1. Cell (r,c) lies at the intersection of row number 'r' and column number ‘c’.
Rook is a chess piece that can in one turn move any number of cells vertically or horizontally. There are ‘m’ rooks (m<=n) placed on the chessboard in such a way that no pair of rooks attack each other. I.e. there are no pairs of rooks that share a common row or a column.
You are given the position of the ‘m’ rooks that are already placed on the chessboard. Your task is to find the maximum number of additional rooks with their positions that can be placed on the given chessboard such that no rook attacks some other rook. Print the positions (cells) of these additional rooks in lexicographical order. If there are multiple ways of placing the maximum number of additional rooks, you should find one that gives the lexicographically smallest sequence of cells after arranging their cells in lexicographical order.
Note :
In lexicographical order, cell (a, b) comes before cell (c, d), if either a < c or (a = c and b < d).
Problem approach
my solution was similar to this
var allSolutions = _.memoize(function(n) {
if (!n) return [];
if (n === 1) return [[[true]]];
var solutions = [];
for (var i = 0; i < n; i++) {
_.each(allSolutions(n-1), function(nMinusOneSolution){
solutions.push(generateSolution(nMinusOneSolution, i));
});
}
return solutions;
});
var generateSolution = function(nMinusOneSolution, i) {
var n = nMinusOneSolution.length + 1;
var newSet = [];
for (var j = 0; j < n-1; j++) {
var row = nMinusOneSolution[j];
newSet.push(row.slice(0).concat(false)); //append empty square to every row
}
newSet.splice(i,0, makeTrueEndingRow(n)); //insert new rook ending row
return newSet;
}
var makeTrueEndingRow = function(x) {
var row = _.times(x-1, function(y) { return false; });
row.push(true);
return row;
}
