i have construct 2d array n,m rows , columns (n & m <= 5), user enters index(location) 2,3 (matrix[2][3]) it's assumed 2 numbers in bounds of matrix. on have find sum of left , right diagonal goes through number, number excluded sum. so example 2d array myarray[3][3] *1* 15 *2* 2 *71* 8 *5* 22 *5* so user enters 1,1 myarray[1][1], in case number 71, sum 1 + 5 + 2 + 5 ... , problem how can find diagonals without going out of bounds. for left top go: row-- column-- while(row >= 0|| column >= 0) left bottom: row++ colum++ while(row < n || column < m) right top: row-- column++ while(row >= 0 || column < m) right bottom: row++ column-- while(row < n || column >=0) (this bad written pseudo-code, sorry) it works fine when enter numbers aren't in top or bottom row, in cases located there program stops. what have pseudocode. first thought should using &&'s instead of ||'s when determining if location out of boun

i have geodesic sphere - created using three.octahedrongeometry - group triangular faces hexagonal faces, can selected. i'm @ loss how approach problem or if it's feasible. insight appreciated. here's example: creategeodesicsphere =-> geometry = new three.octahedrongeometry(200, 3) material = new three.meshbasicmaterial({ color : 0xffffff, shading : three.flatshading, side : three.doubleside, vertexcolors : three.facecolors, overdraw : true }) # explode geometry each face has unique vertices explodemodifier = new three.explodemodifier() explodemodifier.modify(geometry) geodesicmesh = new three.mesh(geometry , material) geodesicfaces = geometry.faces in [0..geodesicfaces.length-1] geodesicfaces[i].color.setrgb(math.random(), math.random(), math.random()) geodesicmesh.position.x

i have 2 lib classes in rails project. both print out error using same syntax i18n.t('.config_error') one file succeeds, other file fails error: i18n::invalidlocaledata: can not load translations /home/hellebusch/.rvm/gems/ruby-2.2.0/gems/activesupport-4.2.0/lib/active_support/locale/en.yml: #<errno::enoent: no such file or directory> i cannot find answer issue. insight great. i believe "." in i18n.t('.config_error') means i18n looking config_error key in namespace of resource being rendered. if rendering posts#show view, i18n looking in posts namespace - aka looking key nested under posts key. does help? posting classes/views call i18n.t('.config_error') helpful.

i ordered build bulean function takes list of numbers , execute "true" if list proper grade list(i.e every number between 0 100) , "false" otherwise. encounter error, caused, believe not thorough acquaintance program. reason why ask here learn doing. i tried few scripts. 1 of them: def isvalidgradelist(i): x in range(0,len(i)+1): if i[x] not in range (0,101): return false else: continue return true as see, code won't way in scripter. how can attend it? appreciate help. thank help. unfortunately, not use "all" built-in function yet, we've not learned how use it. is, however, i've done far. seems working. def areintegers(i): x=0 x in range(0,len(i)): if type(i[x])==int: x=x+1 else: return false return true def isbounded(i): x=0 x in range(0,len(i)): if i[x] in range(0,101): x=x+1 else:
