People can have a first, middle and last name. From these names, monograms can be formed by combining the first letter from each of their names. The monogram is the lowercase version of the first name, followed by the capital version of the middle name's first letter, then the first letter of the last name as a lowercase again. For example, for someone named George paul Alberto their monogram is gPa. Given someone's first, middle and last name, print their monogram.
