Leetcode Problem 640. Solve the Equation

640. Solve the Equation

Leetcode Solutions

Partitioning Coefficients and Constants

  1. Split the equation into left and right parts using the '=' sign.
  2. Initialize variables to store the sum of coefficients of 'x' and constants for both sides.
  3. Iterate through each part and for each term: a. If it contains 'x', extract the coefficient and add/subtract it to/from the sum of coefficients. b. If it's a constant, add/subtract it to/from the sum of constants.
  4. After processing both parts, check for the type of solution: a. If the sum of coefficients is 0 and the sum of constants is not 0, return 'No solution'. b. If both sums are 0, return 'Infinite solutions'. c. Otherwise, calculate the value of 'x' by dividing the sum of constants by the sum of coefficients and return 'x=value'.
