@Prasanth: Since there is no requirement to find the next larger number, you can go for the largest. Extract the digits into an array using modulus and division by 10. Then sort the digits into descending order. Finally, construct the answer by repeated multiplication by 10 and addition.
If you want, you can check to see if the resulting number is greater than the original and return an error code if it is just equal to it. E.g., 8755 already has its digits in decreasing order, so the above algorithm will reproduce 8755.
