Problem 1 (Recursion): Hexadecimal Numbers) Write down the C++ implementation of a recursive function printHex that prints out the hexadecimal (base-16) representation of a decimal (base-10) integer. For example, by calling "printHex(O)" you see "OxO", by calling "printHex(29)" you see "Ox1D". You may assume the input is always non-negative. You can only use one recursive function and cannot call other math library functions. Using built-in printout format conversion is not allowed. Problem 3. Nmeros de la loto Escribir un programa en C++ que genere las combinaciones de 30 nmeros de la loto, includo el power-play para generar los nmeros Usted debe crear un file con los ltimos 30 nmeros jugados de la loto con sus respectivos power-play; los 30 nmeros que su programa generar no deben ser iguales entre si, ni tampoco deben ser iguales a los nmeros que se encuentran en el file; en el caso de presentarse dos nmeros iguales, su programa deber generar los nuevos nmeros, verificando que estos ltimos no sean iguales al resto de los mismos. Su programa deber ser implementado utilizando: file, arrays y de ser necesario struct
