i having difficulties in writing code finding elements in list. i need write program prints "yes" if list contains numbers 1, 2, 3 (all of them) in arbitrary order , "no" otherwise. [10, 2, 4, 15, 3, 6, 1] # yes [1, 17, 2, 45] # no (because number 3 missing) also, need modify program prints "yes" if contains numbers 1, 2, 3 occurring in order listed (but not consecutively) , "no" otherwise.

i've been trying create haskell function gets largest odd integer in list. sounds easy, , sure thought looks i'm stuck! here code, far returns largest number in list including both odd , numbers: maximum :: (ord a) => [a] -> maximum [x] = x maximum (x:xs) = max x (maximum xs) thank in advance help! first of - if have elements in list have problem, function not total (i.e. produces error) - best modify type of result account possibility: also others have mentioned - odd requires constraint integral instead of ord . maximodd :: integral => [a] -> maybe maximodd xs = case filter odd xs' of [] -> nothing xs' -> (maximum xs') the function filter odd removes non-odd elements (i.e. numbers) - pattern match on result account failure. if want work original function code gets lot more tricky: maximum :: integral => [a] -> maximum [x] = x maximum (x:xs) = let y = maximum xs ...

there given numbers 1, 2, ...., b-1 . every number of these can used a[1], a[2], ...., a[b-1] times. from them biggest possible number (from data given) has concatenated, while sum of digits (partial numbers) has divisible b . "digits" of number can of base bigger 2. biggest number of base b has created, concatenating numbers 1...b-1 , a[1]...a[b-1] times each, while sum of used partial numbers/digits has divisible b . for example: there 5 times 1 , 10 times 2 , 4 times 3 , 2 times 4 . stated above, have concatenate biggest number divisible b (here 5 ). give: 44333322222222221111 . concatenating biggest lowest gives needed number, sum divisible 5. 1 times 1 is: 0 because 1 not divisible 2, no numbers should used then. what algorithms or similar problems this? how can approached? at first, can arrange numbers biggest lowest, concatenated number naturally biggest. then, have take least amount of these numbers, sum divisible b . when there can taken dif...
