Check if a string is a subsequence of another string ( using Stacks ) | Function to check if target is a subsequence of string S.
Declare a stack.
Push the characters of target into the stack.
Traverse the string S in reverse.
If the stack is empty.
If S [ i ] is same as the top of the stack.
Pop the top of stack.
Stack s is empty.
