WebB'Toxel likes arrays. Before traveling to the Paldea region, Serval gave him an array a as a gift. This array has n pairwise distinct elements. In order to get more arrays, Toxel performed m operations with the initial array. In the i -th operation, he modified the p_{i} -th element of the (i-1) -th array to v_{i} , resulting in the i -th array ... WebFeb 26, 2024 · C.

WebIn C++, an array is a variable that can store multiple values of the same type. For example, Suppose a class has 27 students, and we need to store the grades of all of them. Instead of creating 27 separate variables, we can simply create an array: double grade [27]; Here, grade is an array that can hold a maximum of 27 elements of double type. WebFeb 25, 2024 · C.
