Z Tower stands near the city of XYJ. We require: a person who has been on top of the tower 5 minutes, must go down; while it's coming down, people
those at the bottom of the tower must wait. Climbing the stairs of the tower and descending
the stairs of the tower take one minute each. Every moment on the stairs
there can only be one person.
Now there is no one at the top of the tower, at the foot of the tower there is a person in line.
After T minutes, B more people will come. After what time (minutes) all people
come out of the tower (the last person to go down the stairs)

I’m pretty sure it is 56,000

You didn't specify any column names, or if you're looking for a sql answer, so with some assumptions, you could write: select * from mytable where mycolumn> =3000

(java)3. the answer is  (c): x[2] = 12; if x is an array with three elements, the first element has index 0. the second index has index 1. the third and final element has index 2.4. the answer is (d) for (int y : x) { system.out.println (y) ; }this is an example of syntax  of a "for-each loop."for each element in the integer array x, use y to indicate the current element to do some code with it.the other choice, (c) for (int x : y) { system.out.println (y) ; }. in a for-each loop, the variable to the right of the colon is the array variable; the one to the left is the control variable.choices (a) and (b) have invalid syntax.5. the answer is (a)  int x = {1, 2, 3, 5, 10}; you need to indicate that it is an array using []. without using [], you are trying to assign an array to an integer. you need to use int[] to indicate integer array.so choice (a) has incorrect syntax.
