Count a Specific Digit

Write a function that counts the number of times a specific digit occurs in a range (inclusive). The function will look like:

digit_occurrences(start, end, digit) ➞ number of times digit occurs

Examples

digit_occurrences(51, 55, 5) ➞ 6
# [51, 52, 53, 54, 55] : 5 occurs 6 times

digit_occurrences(1, 8, 9) ➞ 0

digit_occurrences(-8, -1, 8) ➞ 1

digit_occurrences(71, 77, 2) ➞ 1

Notes

• Ranges can be negative.
• start <= end
