Write a function that tells if the integer number x is present in the vector of integer numbers v.
In order to compare the efficiency of your solution against the efficiency of the solution of the Judge, start searching for x from the lowest positions.
Interface
C++ | bool exists(int x, const vector<int>& v); |
C | int exists(int x, const int v[], int vsize); |
Java | public static boolean exists(int x, int[] v); |
Python | exists(x, v) # returns bool |
exists(x: int, v: list) -> bool |
Observation You only need to submit the required procedure; your main program will be ignored.
