WebNov 18, 2013 · Hence the time complexity is given by: T (N) = N* (T (N-1) + O (1)) T (N) = N* (N-1)* (N-2).. = O (N!) Similarly in NQueens, each time the branching factor decreases by 1 or more, but not much, hence the upper bound of O (N!) For WordBreak it is more complicated but I can give you an approximate idea. WebSep 25, 2016 · The N Queen Problem is one of the best problem used to teach backtracking and of course recursion. Backtracking is a general algorithm which finds all complete solutions to a problem by building over partial solutions. In this process, the problem might reach to a partial solution which may not result into a complete solution. curly leaf willow tree
