Generate an image of a flowchart detailing the following sequence of operations executed within a class named 'Solution'. Begin with the class definition of 'Solution'. Then show a method 'numDecodings' that takes a string 's' as input and returns an integer. Include a set named 'legalstr', which holds integer strings from 1 to 26, and an initialized variable 'ans' set to 0. The function 'dfs' is defined to take a string 's'. If the length of 's' is 0, increment 'ans'. If the first character of 's' is in 'legalstr', recursively call 'dfs' with 's' minus its first character. If 's' is more than 1 character long and the first two characters of 's' are in 'legalstr', then recursively call 'dfs' with 's' minus its first two characters. Finally, call 'dfs' with the input string 's' and return the value of 'ans'.
