-Take a look at your Base64 encoded String, If it starts with
data:image/jpg;base64

design a stack such that getMinimum( ) should be O(1)
... has better space in general. We still have the min stack, but we only pop from it when the value we pop from the main stack is equal to the one on the min stack. We only push to the min stack when the value being pushed onto the main stack is less than or equal to the current min value. This allows...
Random float number generation
...u'll need to employ a more advanced method.
This will generate a number from 0.0 to 1.0, inclusive.
float r = static_cast <float> (rand()) / static_cast <float> (RAND_MAX);
This will generate a number from 0.0 to some arbitrary float, X:
float r2 = static_cast <float> (rand(...

Unpacking, extended unpacking and nested extended unpacking
... we get
((a, b), c) = ((1, 2), ('t', 'h', 'i', 's'))
But now it's clear from the structure that 'this' won't be unpacked, but assigned directly to c. So we undo the substitution.
((a, b), c) = ((1, 2), 'this')
Now let's see what happens when we wrap c in a tuple:
(a,b), (c,) = [1,2],'this' ...
