How to Find Element in Vector in C++? As already discussed, the find() function is used to find the elements in the vector in C++, which finds the very first occurrence of the element in the sequence having a linear time complexity. It takes 3 arguments as input, i.e. first, last, ...
(1) Your function signature says that you are going to return a vector. If you were going to rotate in place you could just have had a void function. (2) You've created a new vector anyway in returning it. (3) Your solutions have time complexity NK (though some of it will be hid...
