How to determine space and time complexity of an algorithm? - i have algorithm, not sure time , space complexity. , for (i = 1 n ) begin r(xi) = random(o, xi, r) i++ end what time , space complexity in above algorithm , why? thanks space , time complexity in proportional size of input. suppose there input array of size n , processing each element once, time complexity o(n) . if utilize info construction store , process intermediate results, array of size n , space complexity o(n) . there many notations complexity , different complexities such log n, n, n^2, n^3, n! . for code time complexity o(n) , space complexity depends on whether have defined( o(n) ) r or passed( o(1) ) parameter. refer here more analysis of algorithms algorithm time-complexity space-complexity

data structures - git: DAG vs. tree? - i've read git uses directed acyclic graph (dag) info structure, each commit node, , things branches , tags pointers nodes. but when seek visualize commit history using tools gitk, looks more tree graph since every parent-child relationship directed 1 way. so, what's difference between dag , tree, regards git? but when seek visualize commit history using tools gitk, looks more tree graph since every parent-child relationship directed 1 way. a dag, tree, can laid out such parent-child relationships one-way. difference between them nodes in dag can have multiple parents. mutual case of in git when merge. merge commit have of commits merged parents. tree doesn't allow nodes have multiple parents. (image source) notice how merge commit c6 has 2 parents, c4 , c5. git data-structures

html - How to debug Font-Awesome icons? - i have been using font-awesome , icons while now, , has been working fine. today, however, displays blank squares instead of icons. have read many other related questions, none of cases apply me. said, worked before, , did not create changes font-awesome files (i using downloaded version of fa, not cdn) or html templates display icons. so want start debugging process. 1 illustration this: <i style="color: orange" class="fa fa-exclamation-triangle"></i> however, cannot find urls in css of affected elements, when inspecting chrome. see on every icon element though, this: .fa-warning:before, .fa-exclamation-triangle:before { content: "\f071"; } where \f071 "blank square" character. so question is: where icons come from, , how can debug no-show fa icons, in general? update i found out \f071 , friends symbols referring icons, stored in font files. fact show blan...
