"No," he replied, "it is a very interesting number it is the smallest number expressible as the sum of two cubes in two different ways."įor this reason 1732 is known as the Ramanujan-Hardy number.Ĭan you verify this with a Python program? Exercise 2ġ729 is the lowest number which can be represented by a Loeschian quadratic form $a^2 + ab + b^2$ in four different ways, with positive integers a and b. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavourable omen. It goes like this: I remember once going to see him when he was ill at Putney. ![]() Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital. There is a little anecdote of the Mathematician G.H. This exercise is about the Ramanujan-Hardy number. The elements to be looped remained the same during the iterations. This refactoring applies to: C Visual Basic Note The Convert to foreach Quick Action refactoring is only available for for loops that contain all three parts: an initializer, condition, and iterator. We changed the list "colours", but our change didn't have any effect on the loop. Convert a for loop to a foreach statement If you have a for loop in your code, you can use this refactoring to convert it to a foreach statement. We still might have done something, we shouldn't have done. This kind of for loop is known in most Unix and Linux shells and it is the one which is implemented in Python. In each iteration step a loop variable is set to a value in a sequence or other data collection. It is usually characterized by the use of an implicit or explicit iterator. This kind of for loop iterates over an enumeration of a set of items. That is, for example, all expressions on the right side of assignment statements get evaluated before the assignments.įinally, we come to the one used by Python. They behave as if all iterations are executed in parallel. I wouldn’t use POST directly as that is not always present. Note you don’t need class attributes etc on these hidden inputs. It is similar to the standard for loop, which makes it easy to convert a. Sure add all the values needed into hidden inputs. Starting with a start value and counting up to an end value, like for i = 1 to 100 The foreach package provides a looping construct for executing R code repeatedly. This kind of for loop is a simplification of the previous kind. This kind of for loop is not implemented in Python! An example of this kind of loop is the for-loop of the programming language C: Generally it has the form:Ī is the initialisation part, Z determines a termination expression and I is the counting expression, where the loop variable is incremented or dcremented. The header of this kind of for loop consists of a three-parameter loop control expression. both the syntax and the semantics differs from one programming language to another.Ĭount-controlled for loop (Three-expression for loop) There are hardly any programming languages without for loops, but the for loop exists in many different flavours, i.e. an iteration statement, which allows a code block to be repeated a certain number of times. Like the while loop the for loop is a programming language statement, i.e. ![]()
