Alok and Bhanu play the following min-max game. Given the expression N = X - Y – Z where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be • 4 • -18 • 9 • 2

An array was given and we were required to write a function : int CalculateThirdHighest(int a[ ]) : which calculates the third highest number in the array. While coding in C remember to calculate the length of array using formulae length of array=sizeof(a)/sizeof(int). Because the number of elements of array were not passed as argument. i want a solution in C/C++ language
