note: unrelated concurrency problem of mutual exclusion, couldn't think of better way of describing problem. i have problem have case want let user select flags, flags mutually exclusive. want describe flags mutually exclusive using data structure, i've thought of has been clunky. basically, want able specify how flags used so: [ -fa | -e | -d ] [ -c ] [ -g | -h ] this should semantically mean, can have 1 of -fa, -e, -d, not 2 or more (however, f can used a, , don't need use both). can either have -c or not, , can have either -g or -h, not both. here's "best" solution. map[flag, mutexgroup] (and inverse, map[mutexgroup, list[flag]]) map[mutexgroup, list[mutexgroup]] what example be map("f" -> 1, "a" -> 1, "e" -> 2, "d" -> 3, "c" -> 4, "g" -> 5, "h" -> 6) map(1 -> list(2, 3), 2 -> list(1, 3), 3 -> list(1, 2), 4 -> list.empty, 5 -> lis...

i looked particular thing, because thought it's quite important , puzzling thing, didn't find on matter. i'm thinking time scaling in wpf , silverlight animations. suppose have doubleanimation lasts 4s , animates property 0 100. it's autoreversed, or there's complementing animation reverses effects, that's not important. let's event triggering animation simple mouseover. here's problem: hover cursor on element. property gets 0 100 in 4s. move cursor away 1s, property gets 100 75, , hover back. property gets form 75 100 in 4s. it's obvious user, animation runs 4 times slower. there way scale time of animation? if want animation run 75 100 in 1s, how that? myself thinking maybe of converter take 4 parameters (absolute beginning , end, actual beginning, , timespan whole interval) , spit out proper time. there more elegant way? i noticed it's not problem when animations fast. human not observe difference in speed when animation runs in 0.2s...

i have array of size 4,9,16 or 25 (according input) , numbers in array same less 1 (if array size 9 biggest element in array 8) the numbers start 0 , algorithm generate sort of checksum array can compare 2 arrays equal without looping through whole array , checking each element 1 one. where can sort of information? need simple possible. thank you. edit: clear on want: -all numbers in array distinct, [0,1,1,2] not valid because there repeated element (1) -the position of numbers matter, [0,1,2,3] not same [3,2,1,0] -the array contain number 0, should taken consideration. edit: okay tried implement fletcher's algorithm here: http://en.wikipedia.org/wiki/fletcher%27s_checksum#straightforward int fletcher(int array[], int size){ int i; int sum1=0; int sum2=0; for(i=0;i<size;i++){ sum1=(sum1+array[i])%255; sum2=(sum2+sum1)%255; } return (sum2 << 8) | sum1; } to honest have no idea return line unfortunately, algorithm not work. arrays ...
