Minimize a string by removing all occurrences of another string | Function to find the minimum length to which string str can be reduced to by removing all occurrences of string K.
Initialize stack of characters.
Push character into the stack.
If stack size >= K . size ( ).
Create empty string to store characters of stack.
Traverse the string K in reverse.
If any of the characters differ , it means that K is not present in the stack.
Push the elements back into the stack.
Store the string.
Remove top element.
Size of stack gives the minimized length of str.
Driver code.
Function Call"
How can the above be solved in Python?
