Would you be able to perform such an improvement? Assuming you can, print any legitimate request.

Use unsigned int for the function’s parameter and unsigned long long int for its returntype. b) Determine the largest Fibonacci number that can be printed on your system.1. Implement Euclidean Algorithm for calculating greatest common divisorFirst write and test a function that calculates the greatest common divisor of two nonnegative integers, as follows: /* precondition: a>=b>=0 *//* postcondition: return d=gcd(a,b) */int EuclidAlgGCD (int a, int b); Then implement the extended Euclidean Algorithm to find not only the greatestcommon divisor of two integers, but also find the integer coefficients that expressesthe gcd in terms of the integers, as illustrated below: /* precondition: a>=b>=0 *//* postcondition: return d=gcd(a,b), s and t are set so that d=sa+tb */int ExtendedEuclidAlgGCD (int a, int b, int & s, int & t);Hi, OCaml programming 1. Create a type slidingTile, consisting of a char matrix and two integers xand y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in thematrix, it slides the tile from the specified location to the empty tile, thenreturns the altered slidingTile. If provided location is not adjacent to theempty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = <fun> that prints a slidingTile on screen with the corresponding characters fromthe matrix. However, print an empty space where the empty tile is instead.
