[ad_1] It’s a generic type, very useful in classes where the content can be of different types. A good example is List, where T specifies what types the elements in the list belong to. Sure, you can use non-generic types such as ArrayList, but that means that when you access an element in the list, … Read more
[ad_1] It’s normal. When you do : $codering = [‘RF-013.12’]; Is same as : $codering = array(‘RF-013.12’); So if you try to use your array like string, php write array instead. If you wanna store [something] (a string with [] character) you need : $codering = “[something]”; If you realy need to store an array, … Read more
[ad_1] to solve questions of this type you must find a formula for spaces and a formula for stars. these formulas tell the computer how many spaces and stars must be printed in each line. that’s all these types of questions need. [ad_2] solved How to print the given ZIG ZAG pattern using C?
[ad_1] Try this : NSSortDescriptor * sortDescriptors = [[NSSortDescriptor alloc] initWithKey:@”name” ascending:YES]; // change your key here NSArray * arrSortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSArray * sortedArray = [yourArray sortedArrayUsingDescriptors:arrSortDescriptors]; NSLog(@”sortedArray %@”,sortedArray); 0 [ad_2] solved Sort a dictionary array when the key is given as the parameter
[ad_1] You have a table called reports and you are extracting a table that consists of the id, user, item_id, and created fields. This new table will only have rows that contain the max value of created for each distinct item_id. This part extracts the fields you want: select a.id, a.user, a.item_id, a.created From a … Read more
[ad_1] You can use standard C function memmove. For example #include <stdio.h> #include <string.h> int main( void ) { char temp[] = “\nHello”; if (temp[0] == ‘\n’) { memmove(temp, temp + 1, strlen(temp)); } puts(temp); } 1 [ad_2] solved How to get rid of ‘\n’ at the beginning of string
[ad_1] What is the number “12” in base-12? 10 Why? The right-most digit is the ones’ digit. The next is the base, 12. The third digit, if there was one, would be 144. Repeat, this time with “5” in base-5. Once again, the second digit is the radix, 5, and the right-most digit is still … Read more
[ad_1] Use the following approach inode_ptr i = NULL; auto it = directories.find(“string”); if ( it != directories.end() ) i = it->second; Maybe it is even better to write inode_ptr i = {}; instead of inode_ptr i = NULL; [ad_2] solved how to retrieve value from map c++ [closed]
[ad_1] T(n) = n log n + (n-1) log (n-1) + … + 1 log 1 + T(0) < n log n + (n-1) log n + … 1 log n + T(0) = ( n + n-1 + n-2 + … + 1) log n + T(0) = n(n+1)/2 ⋅ log n + T(0) … Read more
[ad_1] Remember that + and – have the same precedence, so they are evaluated left-to-right (+ and – are both left-associative operators). So, 90 – 9 + 10 = 81 + 10 = 91. [ad_2] solved Why the expression in java not following BODMAS rule? [closed]
[ad_1] When passing an array as argument, array decays into the pointer of FIRST element of array. One must define a rule, to let the method know the number of elements. You declare char mbuf[16], you pass it to setName(), setName() will not get char[], but will get char* instead. So, the declaration should be … Read more
[ad_1] Let’s say you have person.rb: Class Person ……. end and you have dog.rb: class Dog …….. end If you want to access to Dog class inside Person you have to include it. That means your dog.rb would be: require ‘dog’ class Person def my_method dog = Dog.new() end end require ‘name_of_file_with_class’ This is just … Read more
[ad_1] I do not fully understand what you wanted to achieve but i think is one of the following 2: 1.return a continuous range of value between minimum and maximum. In this case you can use range and do not pass Y as input param. def Z(minimum,maximum): Y = range(minimum, maximum) return Y print Z(2,4) … Read more
[ad_1] Use this it works….. create boolean variable as global within class but outside methods. boolean flag=true; and add this clicked method. @Override public void onClick(View v) { if (flag){ power.setVisibility(View.GONE); flag=false; } else { flag=true; power.setVisibility(View.VISIBLE);} } }); mute always visible , because you performing visibility with power that why the result coming same. … Read more
[ad_1] NSMutableString.string is a hack. It “works” for the same reason that myString.length and [myString length] produce the same result. However, since dot notation is not used with an actual property, it is an abuse of the language feature, because properties have a different semantic. For example, when you access a property multiple times, you … Read more
