[ad_1] Update: Now the situation looks a bit different as you updated the question. Here’s a quick snippet thrown together using pandas and numpy (for the sake of simplicity we replace missing ratings with zero): import numpy as np importport pandas as pd from itertools import combinations df = pd.DataFrame(critics).T.fillna(0) distances = [] for critic1, … Read more

[ad_1] The Unix API is C (as is the Windows API); any calls into Unix will look like C. That doesn’t stop you from using C++, however: if the function requires a char const*, for example, you can call std::string::c_str() on an std::string. Whether you want the Unix function (e.g read()) or the C++ (>> … Read more
[ad_1] Both. In some rows, t2.number is number and in others t3.number is number. The result of the union all in a single result set. The result set doesn’t know the origin of the values in any particular column (although you could include another column with this information). 3 [ad_2] solved Selecting the right column
[ad_1] The best way I would see to do this would be to use Vectors. This is not like arrays where you need a defined size in order to proceed. Vectors can grow and shrink. See [http://docs.oracle.com/javase/7/docs/api/java/util/Vector.html] for more details. Basing this off the code you have already given I would recommend the following: import … Read more
[ad_1] This can be solved with a breadth first search (BFS) in the graph. This algorithm gives you back a tree whose root is the city you start with and the unique path from there to any other node/city is the one with the fewest possible hops. If you need this information for all your … Read more
[ad_1] The part you’re missing is the return type of the function, and then to actually return that value from the function. At the moment you have void compute_sum(int limit) // compute_sum function { int sum_to_limit; sum_to_limit = limit * (limit + 1) / 2; } A function prototype in C looks pretty much like … Read more
[ad_1] First off, I notice two problems: You have a syntax error in the parameter list to $.post You probably don’t want to do this: setTimeout(chatcom_load_one(id), 1000); Here’s an updated version of your code with these errors fixed: function chat_com_one(id) { $(‘#chatcom’).show(‘fast’); (function chatcom_load_one(id) { $.post(‘sendchat2.php’, { option: ‘chatcom_load_one’, tocom: id }, function (data) { … Read more
[ad_1] Reason for specific output. Since you don not have a break; for switch conditions you fall through all the switch cases from the first match found From this tutorial, When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. If … Read more
[ad_1] In the following statement, fscanf will return 3 if all the input operations are successful. while( fscanf(fp, “The different between frame %d and %d :%d”, &i, &j, arr) == 1 ){ Change it to: while( fscanf(fp, “The different between frame %d and %d :%d”, &i, &j, arr) == 3 ){ Another thing… You have … Read more
[ad_1] The only way the problem can exist given the posted code, if the reported exception/line is correct, is when “Somerecords” is not really creating a List<Object[]> object – but a List containing non-Object[] elements. One reason could be the method in question is typed to return a non-generic List, filled with double values. Java … Read more

[ad_1] Take ML course on coursera. It is a good introductery into ML algorithms which will tell you what ML could do\some general approaches: https://www.coursera.org/course/ml Also to get a broader picture I suggest coursera’s DataSciense course: https://www.coursera.org/course/datasci Finally a good book is Mahout in action – it is more about solving practical matters with mahout … Read more
[ad_1] I think DATEDIFF would be your best option. I know you are looking for the difference in time within the same day, but couldn’t you just pass DATEDIFF two DateTime types with the same date, but different times? // Should return 300 DATEDIFF(mi, ‘2015-02-19 08:00:00’, ‘2015-02-19 13:00:00’) 2 [ad_2] solved How do I get … Read more
