Let’s add some tracing so we can see order-of-operations: import sys def findIdx(ary, tgt): retval = ary.index(tgt) print(‘First instance of %r in %r is at position %r’ % (tgt, ary, retval), file=sys.stderr) return retval data1 = [1.48, -4.96] i = 0 mn = data1[1] k = findIdx(data1, mn) data1[i], data1[k] = data1[k], data1[i] print(“Prior lookup: … Read more
You can do this: var str = “asp,mvc,c#,wpf”; var anotherStr = “<b>asp</b>,<b>wpf</b>”; var myArr = anotherStr.Replace(“<b>”, “”).Replace(“</b>”, “”).Split(‘,’); foreach (string value in myArr) { str = str.Replace(value, “<b>” + value + “</b>”); } Console.WriteLine(str); 2 solved Replace the particular part of string?

First part, mobile carriers: They will always know which server you are connecting to, because it’s them who establish this connection.

You can define variables with the same names in different scopes. The first variable i is defined in the scope of the main function. In the loop there is another implied nested and anonymous scope for the variables you declare for the loop. For the compiler, the code for(int i = 1; i <= 10; … Read more
You could efficiently extract the month with bitwise operations if you represented the date in a binary format, e.g., 5 bits for the day of the month, 4 bits for the month number, and the rest for the year, rather than as decimal digits. For your example, the date would be (2011 << 9) + … Read more
