/*
    Max Value in Array
    
    Take as input N, the size of array. Take N more inputs and store that in an array. 
    Write a function which returns the maximum value in the array. Print the value returned.
    1.It reads a number N.
    2.Take Another N numbers as input and store them in an Array.
    3.calculate the max value in the array and return that value.
    
    Input Format:  First line contains integer n as size of array. 
                   Next n lines contains a single integer as element of array.

    Constraints:  N cannot be Negative. Range of Numbers can be between -1000000000 to 1000000000
    
    Output Format: Print the required output.

    Sample Input: 4
                  2
                  8
                  6
                  4
    
    Sample Output: 8

    Explanation: Arrays= {2, 8, 6, 4} => Max value = 8 .
