Sequential search in an array

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.
