So I am new to Java coding. I tried my hand at a grade XII Board exam program. It reads, "Given two positive numbers M and N, such that M is between 100 and 10000 and N is less than 100, find the smallest integer that is greater than M and whose digits add up to N. For example, if M = 100 and N =...
