Leetcode Problem 2307. Check for Contradictions in Equations
2307. Check for Contradictions in Equations
Leetcode Solutions
Union Find with Value Tracking
Initialize a Union Find data structure with methods to add nodes, find the root of a node, and union two nodes with a value.
Iterate through each equation and its corresponding value.
For each equation, find the roots of the two variables involved.
If the roots are the same, calculate the expected value based on the Union Find structure and compare it with the given value. If they differ significantly, return true for a contradiction.
If the roots are different, union the two variables with the given value.
If no contradictions are found after processing all equations, return false.
