2259. Remove Digit From Number to Maximize Result
Problem Explanation
Explanation:
To maximize the resulting number, we can remove the first occurrence of the given digit, as removing any other occurrence would result in a smaller number. We can find the index of the first occurrence of the digit in the number and then remove it to obtain the maximum possible number.
- Find the index of the first occurrence of the digit in the number.
- Remove the digit at that index to obtain the maximum number.
Time Complexity: O(n) where n is the length of the input number.
Space Complexity: O(1)
