Friday puzzle

Final Friday of my week & a maths puzzle...
Your task is to create every number from 1 to 50.
You can use only the digits 1, 2, 3 and 4 once in each and the operations + - * / .
You can use the digits as powers, and you must use all of the digits 1, 2, 3, 4

Here are some examples:

1 = (4-3) / (2-1)
20 = 42 +3 +1
68 = 34 * 2 * 1
75 = (4+1)2 * 3
 
1 to 50 was easy, so I did 51 to 100

51 = (12 * 4) + 3 OR (42+1) x 3
52 = 43 - 12
53 = (1 + 4!) * 2 + 3
54 = (13 * 4) +2
55 = 34+ 21
56 = (1 + 3 + 4!)2
57 =(1+4)! / 2 - 3 OR (4 + 2) / .1 - 3
58 = (31 * 2) - 4
59 = (21 * 3) - 4
60 = 34 - 21
61 = 43 - (1 + 2)
62 = 43 - (1 * 2)
63 = 43 - (2 - 1)
64 = (2 - 1) * 43
65 = (2 - 1) + 43
66 = (2 * 1) +43
67 = (34 * 2) -1
68 = 34 * 2 * 1
69 = (34 * 2) + 1
70 = 43 + (1 + 2)!
71 = ((4! / 2) * 3!) - 1
72 = 24 * 3 * 1
73 = (3 * 4!) + (2 - 1)
74 = (3 * 4!) + (2 * 1)
75 = (4+1)2 * 3
76 = (41 * 2) - 3!
77 = ((4! + 1) * 3) + 2
78 = (4! + 2) * 3 * 1
79 = 34 - (2 * 1)
80 = 34 - (2 -1)
81 = (4! + 1 + 2) * 3
82 = 34 + (2 - 1)
83 = 34 + (2 * 1)
84 = 34 + 2 + 1
85 = (43 * 2) - 1
86 = 43 * 2 * 1
87 = (21 * 4) + 3
88 = (43 + 1) * 2
89 = (3!)! / (2 * 4) - 1
90 = (1! + 2!) * (3! + 4!)
91 = (23 * 4) - 1
92 = 23 * 4 * 1
93 = (23 * 4) + 1
94 = (1 + 3)4! - 2
95 = 3!*(24) - 1
96 = (12 * 4!) /3
97 = 4(3! - 2)! + 1
98 = (1 + 3)4! + 2
99 = 123 - 4!
100 = (3 / .12) * 4
 
Any plans to post the answers to these questions?

I've got a load of people waiting on an answe to the jail/hats one!
 
@stebiggy Just click the spoiler button & all will become clear (maybe)

Is it white because...

Man 1 could see the hats of the other two. He would know he was wearing white if the others both had a red hat as there were only two reds so 2 and 3 (blind) can't both be wearing red.

Man 2 could see the hats of the other two. He now knows that if 3 (blind) has a red hat then he must have a white hat (from above) but he says he doesn't know, so 3 (blind) can't be wearing a red hat.

Man 3 (blind) can then suss out that he must be wearing a white hat.
