for uva problem, working on constructing rooted tree following constraints. a tree of depth d means tree should contain @ least 1 node d distance away root , there no node of more d distance root. the degree of node of tree cannot greater v . degree of node measured number of nodes directly connected to, via single edge. the goal determine maximum possible number of nodes. find that, looking sum on v^i , ranges 0 d. summation appears give maximum number of nodes correctly in many cases, i'm assuming it's correct. however, question states 'if not possible construct tree, print -1'. can think of no possible case might occur. think supposed be printed when user enters v , d outside range given in problem. maximum number of nodes = 1 + ( v * ((v-1)^(d-1)) ) , v>=2, d>=1 . explanation: 1 root node, 1st level can have v nodes, 2nd level on wards can have v-1 nodes, restrict maximum degree v. it not possible construct tree if: case 1: d=1 ,...

i need create struct storing 4 points. wanted create point variable, looks can't use system.drawing in console application. should use? you should add reference system.drawing.dll , add using system.drawing; using system; using system.collections.generic; using system.linq; using system.text; using system.drawing; namespace consoleapplication5 { class program { static void main(string[] args) { point point = new point(); } } }

so search filenames os.walk() , write resulting list of names file. know more efficient : opening file , writing each result find them or storing in list , writing whole list. list big wonder if second solution work. see example: import os fil = open('/tmp/stuff', 'w') fil.write('aaa') os.system('cat /tmp/stuff') you may expect see aaa , instead nothing. because python has internal buffer. writing disk expensive, has to: tell os write it. actually transfer data disk (on hard disk may involve spinning up, waiting io time, etc.). wait os report success on writing. if want write small things, can add quite time. instead, python keep buffer , actually write time time. don't have worry memory growth, kept @ low value. docs : "0 means unbuffered, 1 means line buffered, other positive value means use buffer of (approximately) size (in bytes). negative buffering means use system default, line buffered tty devices , buffered o...

i want develop app detects how far user/device points on map. calculating distance easy, when close 30meters need precise possible. basically want lights on ui brighter closer target/point. how achieve if gps position bounces around 5-10 meters or more? ideas on how approach this? thanks! in general there inaccuracy position, , indeed meters, bouncing there , rather impossible rid of it, anyways, 1 suggestion collect last few (3-10 , logic really) locations , calculate average them. fast movements position lagging of course, when doing slow movements position shown should more stable.. of course have additional logic on determining movement direction, , accepting location change towards faster etc.

in order save time, i'd know if there's professional way terminate unresponsive ncurses program (from terminal) raw() setting turned on. here, ctrl+c won't help. example progam: #include <ncurses.h> int main() { initscr(); raw(); while(1) { printw("yello\n"); } refresh(); endwin(); return 0; } whenever hit control-c ( c-c ) combination, terminal parses , sends signal (sigint) whatever application running in foreground. control-c has no special meaning operating system, terminal. when call ncurses' raw() or cbreak() function, instructs terminal ignore these special characters , pass them on directly whatever's running in foreground, instructing terminal application "knows it's doing". so yes, have "manually" (i.e. terminal) kill running application: ps aux | grep your_executable_name kill the_pid yes, can while in tty. , yes, can jam whole system if lock...
