Solution: Compare Version Numbers
Understand how to compare two version number strings by splitting them into revisions and using two pointers to evaluate each segment. This lesson guides you through handling missing revisions, converting strings to integers, and returning comparison results efficiently. Learn to implement this pattern to solve related coding challenges with clarity and precision.
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
