Identifiers: Letters, numbers, underscores, and $ symbols; (name1)cannot start with a number, cannot use illegal characters, such as:#,% ... such askeywords cannot be used, spaces are not allowed, and case sensitivity is required;For the writing of identifiers, we should develop a good habit. For example: Class name: The first letter of each word is capitalized; Method Name: The first letter is lowercase, the first letter of the second word is capitalized;Expressions: The composition of identifi

result is the same as the original result, the refactoring ends.3, if the test results are different from the original, in the testing and debugging process, the old algorithm as a comparative reference standard. corresponding to each test case, the new and old 2 algorithms are executed, and observe whether the results of 2 are the same. This can help you see which test case is in trouble and what kind of trouble it has.Summary: Optimization of algorithmsRefactoring to improve existing code des

Given the integer matrix A of the M row N column, if the non-boundary element of a a[i][j] is greater than the next 4 elements, then the element A[i][j] is the local maximum value of the matrix. The subject requires the full local maxima of the given matrix and its location.Input format:The input gives the number of rows m and the number of columns N (3Output format:Each line outputs a local maximum value in the format of the element value row number column number, where the row, column number s

not to assign a value, cannot alter the object itself, so it is also considered immutable object.the parameter passing of function from the view of dynamic typeThe argument of a function is passed, essentially a reference. For example:def f (x): = print= 1f (a)print AThe parameter x is a new reference to the object referred to by a. If the argument is an immutable (immutable) object, the A and x references are independent of each other. The operation on parameter x does not affect refere
