I was converting it to number then applying the operations, then I tried generating all the substring and printing the odd largest, but this was the best and easy solution.

class Solution {
public String largestOddNumber(String num){
for(int i=num.length()-1;i>=0;--i)
if((num.charAt(i)-'0')%2==1)
return num.substring(0, i+1);
return " ";
}
}
Tc=0(n);
Sc=0(n);
🎉❤
