Problem 54275. Get twenty-four

  • Created by CXD
Inpur four integers in 1 to 10, you may use plus, minus, multiply and divid to get 24. Note that every integer should be used once and only once. Brackets are of no limit, and the result should exactly be 24 once you calculate by hand. (Calculation in computer will lead to a tolerance to the computer precision.)
You need to return a format and a vector with the same four integers, such that you can print the expression.
E.g., input x = [5 5 7 7]
you may return f = '(%d*%d)-(%d/%d)'
and z = [5 5 7 7]
so 24 is obatined by eval(sprintf(f,z)).
The answer is not necessary unique, e.g., other acceptable answers are
f = '(%d*%d)-(%d*%d)'
z = [7 7 5 5]
and f = '(%d-%d)*(%d+%d)'
z = [7 5 7 5]
