You have to implement stack operations push(), pop() and getMin(). push() function simply adds the element to the stack. pop() function returns the most recent element pushed into the stack, return -1 if the stack is empty. getMin() function returns the minimum element among the present elements in the stack. For push operation '1' is used. Eg 1 2 means push(1), 1 1 means push(1) For pop() operation '2' is used For getMin() operation '3' is used
