The default template parameter of `uniform_int_distribution` is int. As the constructor uses the same type, the passed argument `window` will be implicitly narrowed down and get overflow when its value is greater than INT_MAX. In that case, the random number generator has UB.

Uniform distribution
Invoking
uniform_input_unsorted(n,4294967295)resulted in callingstd::uniform_int_distribution<int>(1,-1), which is an undefined behavior. Fixed it by changing the type tostd::uniform_int_distribution<size_t>.--small flag
parser.add_argument('--small', action="store_false", ...)assigned a default value toargs.smallso the scripts would always use the small datasets regardless of--smallflag. Besides,store_falseseemed to have the opposite behavior to the literal meaning of this flag.
