Compare Version Numbers
Understand the two pointers technique to compare version numbers by evaluating integer revisions from left to right. Learn how to treat missing revisions as zeros and return comparison results using a clear, step-by-step approach. This lesson helps strengthen your problem-solving skills for coding interviews involving string and integer manipulations.
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
