The keys of the dictionary are single letters and the corresponding values are integers, e.g., {'b': 5, 'a': 6, 'c': 31, For each key:value par in the dictionary the function prints a series of stars followed by a space, followed by the key. The number of stars printed is given by the value corresponding to the key. The keys are printed in alphabetical order. Note that the key is not printed if the corresponding value is a number less than 1 For example, the following code print("1.") draw histogram('a: 2, ' 7, 'b':5 print() print("2.") prints 1. s* a s*** c 2
