In C and C + +, there are three basic ways to use the storage area:[Static Memory]In the static store, the connector (linker) Allocates space for the object according to the requirements of the program. Global variables, static class members, and

There are 5 main areas of memory allocation for C languages:1. Stack area : When executing a function, a local variable within the function (not including the static variable), the function return value of the storage unit is created on the stack

Problem description For an array, the range function is defined below: range (A) = max (a)-min (A) + 1; for example, suppose a = {1, 2, 3, 4, 5}, then range (A) = 5-1 + 1 = 5. now, given an array A (length ≤ 100000), you are going to calcalute the

Find the substring with the longest repeat times in a string and calculate its repeat times. For example, the string "ABC fghi bc kl abcd lkm abcdefg" and returns "ABCD" and 2. Because the question requires that the longest substring be repeated at
