Leetcode Problem 964. Least Operators to Express Number

964. Least Operators to Express Number

Leetcode Solutions

Define a recursive function that takes the current target and the number of operations performed so far as arguments.
If the target is already in the memoization table, return the stored result to avoid redundant calculations.
If the target is less than x, handle the base case by returning the minimum of either adding or subtracting x/x to reach the target.
Calculate the number of times x can be multiplied without exceeding the target (the power of x).
Consider two scenarios: adding x to the power calculated in step 4 to reach the target, or subtracting from the next higher power of x to reach the target.
Recursively calculate the minimum number of operations for both scenarios and update the memoization table.
Return the minimum number of operations found.
