Give me a code to check if it is possible to transform one string to another and the other steps required given the following:
Check if it is possible to transform one string to another | function to check if a string can be converted to another string by performing following operations.
calculates length.
mark 1 st position as true.
traverse for all DPi , j.
if possible for to convert i characters of s1 to j characters of s2.
if upper_case ( s1 [ i ] ) == s2 [ j ] is same.
if not upper then deletion is possible.
driver code"
How can the above be solved in Python?
