i have set of 2d coordinates. can positive, negative , in fractions well. points like, 50.2345,-23.452 1.345,-14.206 so on , forth. question if plot these coordinates on graph, how determine whether line intersect form loop or remain zig zag line(without intersecting itself). this can calculated nested loop. assume have 5 points: [0,0],[1,1],[2,1],[2,0],[0,1] this gives 4 edges, last of overlap first. edge ([0,0],[1,1]) intersect edge ([2,0],[0,1]). iterate on each edge (line segment) , test intersection other line segments. pseudocode: for(edge1 in edges) { for(edge2 in edges) { if ( testintersect(edge1,edge2) ) return true; } } return false;

in python can a_set.pop() , remove element set , catch in variable. there way same thing set in ruby? the best way research question @ docs. google search 'ruby set' find doc ruby set class . can review of available instance methods. as can see, set "a collection of unordered values no duplicates." since it's unordered, it's not designed values @ particular locations within set, including last value. you convert array using #to_a , use #pop on array, since order of set not guaranteed, might not end value you're expecting. edit: interestingly, pop in python deletes , returns "an arbitrary element." see that's looking for. while not available built-in method in ruby set, suppose implement using array#sample , grabs random element array, , delete set: class set def pop el = self.to_a.sample self.delete(el) el end end

given data frame df <- data.frame(a = sample(c(1,0), 30, replace = true), b = sample(c(2,3), 30, replace = true), c = sample(c(4,5), 30, replace = true)) and expression captured lazy() argument in lazyeval package library(lazyeval) toeval <- lazy(c(a,b)) i want data frame 2 variables , b instead of 1 concatenated vector, given with result <- lazy_eval(toeval, df) an unelegant version instantly comes ones mind df_result <- data.frame(a = result[1:(nrow(df))], b = result[(nrow(df)+1):(nrow(df)*2)]) better ideas appreciated! you can try: toeval <- lazy(list(a,b)) data.frame(do.call(cbind, lazy_eval(toeval, df)))

i have following 2 dimensional bitmap: num = 521 arr = [i == '1' in bin(num)[2:].zfill(n*n)] board = [arr[n*i:n*i+n] in xrange(n)] just curiosity wanted check how more space take, if have integers instead of booleans. checked current size sys.getsizeof(board) , got 104 after modified arr = [int(i) in bin(num)[2:].zfill(n*n)] , still got 104 then decided see how strings: arr = [i in bin(num)[2:].zfill(n*n)] , still shows 104 this looks strange, because expected list of lists of strings waste way more memory booleans. apparently missing how getsizeof calculates size. can explain me why such results. p.s. zehnpard's answer, see can use sum(sys.getsizeof(i) line in board in line) approximately count memory (most not count lists, not important me). see difference in numbers string , int/bool (no difference int , boolean) the docs sys module since python 3.4 pretty explicit: only memory consumption directly attributed object accounted for,...
