Given that i^j=N, you can solve the equation for j by taking the log of both sides:j log(i) = log(N) or j = log(N) / log(i). So the algorithm becomes for i=2 to N { j = log(N) / log(i) if((Power(i,j)==N) print(i,j) } Note that due to rounding errors with floating point calculations, you might … Read more
The first declaration creates a list with an underlying array with a size of 5. The second declaration copies data from the passed array to the underlying array in the list. So the second declaration needs to: Create an empty array Copy the values in that array to another array Since it’s also harder to … Read more
The way that the ++ “postfix” increment operator works involves first performing a conversion to number type. The value of that conversion is always the return value from the operation, even if that value is NaN. solved Why NaN is returned by a post-increment operator? [closed]
Assuming ICANON is a bit-mask, i.e. an integer with bits set to represent some feature, that statement will make sure those bits are not set in c_lflag. This is often called “masking off” those bits. The operation is a bitwise AND with the bitwise inverse (~ is bitwise inverse). So, if the value of c_lflag … Read more
You forgot to put the field name before “NOT IN” : SELECT * FROM users WHERE username IN (‘aniket27′,’deepakrajak’,’bhawana’,’Mehul13′,’sanchayeeta’,’shivajidutta’,’anamika_4a’,’parekh’,’anupamkumar’) AND username NOT IN (‘aniket27’) ORDER BY id DESC LIMIT 2 solved How to use IN & NOT IN same query [closed]
Immutable means, that class does not contain any method that would change it’s internal state. Example of immutable class: class ImmutableInteger { private final int value; public ImmutableInteger(int value) {this.value = value;} public int value() {return value;} public ImmutableInteger add(int a) { // instead of changing this state, we will create new instance with result … Read more
Since you have a List<object> that actually contains List<List<Player>> and you want to get a list of players in one big list. Unfortunately for some external reason you are unable to change the API to give you sensibly typed data, you need to go through a couple of hoops. So given this: List<object> players = … Read more
Why not use a dictionary for that? This way you could add and remove values in/from your dictionary just as you wanted. my_dict = { ‘var1’: 0, ‘var2’: 0, … } You can delete by doing my_dict.pop(‘var1’) if you need the value back or del my_dict[‘var1’] otherwise and add items with my_dict[‘var3’] = 0. 2 … Read more

You need to end the recursion at some point: int factorial(int b) /*Function definition*/ { if (b == 0) return 1; return b*factorial(b-1); } 2 solved why does this recursive program for factorial not work? [closed]
I’m intrigued as to who “they” are in this line : “This really frustrates me and they won’t listen to me.” ? It reads as if you’re referring to the rest of the scrum team. If so, I suggest you need to get to a “we” footing as soon as possible and work on communication. … Read more
