$8\mathrm{.}1$: Frequency

Design and implement an application that reads an arbitrary number of integers that are in the range $0$ to $50$ inclusive and counts how many occurrences of each are entered. After all input has been processed, print all of the values $($with the number of occurrences$)$ that were entered one or more times. The output should be one frequency count per line with the following format:

$3$ occurrences of $2$

$7$ occurrences of $5$
