i'd appreciate one. have similar data below. df$a df$b 1 . 1 . 1 . 1 6 2 . 2 . 2 7 what need fill in df$b each value corresponds end of run of values in df$a . example below. df$a df$b 1 6 1 6 1 6 1 6 2 7 2 7 2 7 any welcome. it seems me missing values denoted . . better read dataset na.strings="." missing values na . current dataset, 'b' column character/factor class (depending upon whether used stringsasfactors=false/true (default) in read.table/read.csv . using data.table , convert data.frame data.table ( setdt(df1) ), change 'character' class 'numeric' ( b:= as.numeric(b) ). result in coercing . na (a warning appear). grouped "a", change "b" values last element ( b:= b[.n] ) library(data.table) setdt(df1)[,b:= as.numeric(b)][,b:=b[.n] , = a] # b #1: 1 6 #2: 1 6 #3: 1 6 #4: 1 6 #5: 2 7 #6: 2 7 #7: 2 7 or dplyr library(dplyr) df1 %>% g...

can explain me why output program below, if input values: 5, 222, 2043, 29, 2, 20035 22222? i'm trying solve on paper , can't result. #include <iostream> using namespace std; int n=0; int x=0; int s=0; int i=1; int main() { cin >> n; for(i=1; i<=n; i++) { cin >> x; int nr=1; while(x>9) { nr=nr*10; x=x/10; } s=s+x*nr; } cout << s; return 0; } your while loop divides x 10 every time. , since you're dealing integers, shifts decimal number 1 right: 7234 -> 723 . untill smaller 10, or in other words, there 1 (the first) digit left: 7. multiplies again 10^(times divided 10): 7000. means code whitin for-loop makes first digits 0 in each x. in end you'll have: 200 + 2000 + 20 + 2 + 20000

i'm trying set x-axis limits different values each facet seaborn facetgrid distplot. understand can access axes within subplots through g.axes , i've tried iterate on them , set xlim with: g = sns.facetgrid(mapping, col=options.facetcol, row=options.facetrow, col_order=sorted(cols), hue=options.group) g = g.map(sns.distplot, options.axis) i, ax in enumerate(g.axes.flat): # set every-other axis testing purposes if % 2 == 0[enter link description here][1]: ax.set_xlim(-400,500) else: ax.set_xlim(-200,200) however, when this, axes set (-200, 200) not every other facet. what doing wrong? mwaskom had solution; posting here completeness - had change following line to: g = sns.facetgrid(mapping, col=options.facetcol, row=options.facetrow, col_order=sorted(cols), hue=options.group, sharex=false)

i want make table changes row color based on row's content. therefore use following code. did myself , seems cause of problem ;) because part row background set seems not work intended: not row goodfriends changes it's color 1 above. see placed system.out.println(row.getitem()); before color set sure row right 'row'. - , is. @ point have no idea why wrong row colored while row reference @ runtime (the right one). any ideas? persontable.setrowfactory(new callback<tableview<person>, tablerow<person>>() { person person; int counter = 0; @override public tablerow<person> call(tableview<person> tableview) { tablerow<person> row = new tablerow<>(); if (counter < tableview.getitems().size() && (person = tableview.getitems().get(counter)) != null) { row.setitem(person); counter++; } if (row.geti...

using regex, how match except 4 digits in row? here sample text might using: foo1234bar baz 1111bat asdf 0000 fdsa a123b matches might following: "foo", "bar", "baz ", "bat", "asdf ", " fdsa", "a123b" here regular expressions i've come on own have failed capture need: [^\d]+ (this 1 includes a123b) ^.*(?=[\d]{4}) (this 1 not include line after 4 digits) ^.*(?=[\d]{4}).* (this 1 includes numbers) any ideas on how matches before , after 4 digit sequence? you haven't specified app language, practically every app language has split function, , you'll want if split on \d{4} . eg in java: string[] stufftokeep = input.split("\\d{4}");

suppose have set of 2d line segments connected. need algorithm finds outermost segments in set. is, minimal subset bounds same region. note: not same finding convex hull of points making segments. edit: on top initial set of segments. below same outline interior segments deleted. (ignore little grey crosses, they're mark intersection points.) how pencil...? find leftmost vertex (minimum x). if there's more one, choose lowest of them (minimum y). there no vertex below current one, take direction 'downwards' reference. find edges going current vertex , calculate directions (bearings). find 1 makes smallest positive angle (counter-clockwise) reference direction. outline segment. select other end new 'current' vertex , set direction from vertex recent one new reference direction. proceed step 2 until arrive start vertex. remove unvisited segments. remove orphaned vertices (if appeared in step 5).
