Solution: Compare Version Numbers
Understand how to compare two version strings by splitting them into revisions and using two pointers to traverse and compare integer values. This lesson teaches you to handle missing revisions by treating them as zero, and efficiently determine if one version is less, greater, or equal to the other, improving your problem-solving skills with array and string comparison techniques.
We'll cover the following...
Statement
Given two version strings, version1 and version2, compare them. A version string is composed of revisions separated by dots ('.'). Each revision’s value is determined by converting it to an integer, disregarding any leading zeros.
Compare the two version strings by evaluating their revision values from left to right. If one version string contains fewer revisions than the other, treat each missing revision as 0.
Return the result of the comparison as follows:
Return
if version1is less thanversion2.Return
