-

Implement a function that takes a string of four digits as its argument, with each digit from 1 ──► 9 (inclusive) with repetitions allowed, and returns an arithmetic expression that evaluates to the number 24. If no such solution exists, return "no solution exists."

-

Rules:

- Only the following operators/functions are allowed: multiplication, division, addition, subtraction - Division should use floating point or rational arithmetic, etc, to preserve remainders. - Forming multiple digit numbers from the supplied digits is disallowed. (So an answer of 12+12 when given 1, 2, 2, and 1 is wrong). - The order of the digits when given does not have to be preserved. -

Example inputs:

-solve24("4878"); -solve24("1234"); -solve24("6789"); -solve24("1127"); -

Example outputs (strings):

-(7-8/8)*4 -3*1*4*2 -(6*8)/(9-7) -(1+7)*(2+1) +
