Given a pattern containing only I's and D's. I for increasing and D for decreasing.
Devise an algorithm to print the minimum number following that pattern.
Digits from 1-9 and digits can't repeat.
Input:DOutput:21Explanation:D is meant for decreasing,So we choose the minimum numberamong 21,31,54,87,etc.
Input:IIDDDOutput:126543Explanation:Above example is self- explanatory,1 < 2 < 6 > 5 > 4 > 3 I - I - D - D - D
You don't need to read input or print anything. Your task is to complete the function printMinNumberForPattern() which takes the string S and returns a string containing the minimum number following the valid pattern.
Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)
