Compare Version Numbers
Explore how to compare two version strings by breaking them into integer revisions and evaluating them from left to right using the two pointers approach. This lesson helps you handle varying revision lengths and understand integral comparison techniques to solve version number problems efficiently.
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
