# 2259. Remove Digit From Number to Maximize Result

## 思路
check the next digit
we can just remove the **leftmost** digit if it's followed by a larger number. If we cannot find such case, we remove the last occurence of digit.
## Code

class Solution {
    public String removeDigit(String number, char digit) {
        char[] digits = number.toCharArray();
        int lastDig = 0;
        for(int i = 0;i < digits.length;i++){
            if(digits[i]==digit){
                lastDig = i;
                if(i+1==digits.length || digits[i+1]>digits[i]){
                    return number.substring(0, i) + number.substring(i+1); 
                }
            }
        }
        return number.substring(0,lastDig) + number.substring(lastDig+1); 
    }
}
