This problem combines range() and print(). You'll read an integer N and print all integers from to N on a single line with no spaces between them. For example, if N is , you print: 123. If N is , you print: 12345.
No spaces, no newlines between numbers. Just the digits concatenated together. Go read the problem statement on HackerRank. Think about which print parameter removes spaces between items. Then come back here for the walkthrough.
