java programme solution

Question

Write a program that reads the integers between 1 and 100 and counts the

occurrences of each. Assume the input ends with 0

Answer 1

I would say the best solution here would be tp use a dictionary. Loop over each item in the list of numbers. For each number, check to see if it already exists in the dictionary as a key, if it does, increment its value by 1. Otherwise add a new key and set its value to 1.
