<p>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."</p> <p>Implement a function that takes a string of four digits as its argument, with each digit from 1 to 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."</p>
<p>Rules:</p>
Only the following operators/functions are allowed: multiplication, division, addition, subtraction ### Rules:
Division should use floating point or rational arithmetic, etc, to preserve remainders. <ul>
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). <li> Only the following operators/functions are allowed: multiplication, division, addition, subtraction. </li>
The order of the digits when given does not have to be preserved. <li> Division should use floating point or rational arithmetic, etc, to preserve remainders. </li>
<p>Example inputs:</p> <li> 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). </li>
<code>solve24("4878");</code> <li> The order of the digits when given does not have to be preserved. </li>
<code>solve24("1234");</code> </ul>
<code>solve24("6789");</code>
<code>solve24("1127");</code> | Example input | Example output |
<p>Example outputs (strings):</p> | --- | --- |
<code>(7-8/8)*4</code> | <code>solve24("4878");</code> | <code>(7-8/8)*4</code> |
<code>3*1*4*2</code> | <code>solve24("1234");</code> | <code>3*1*4*2</code> |
<code>(6*8)/(9-7)</code> | <code>solve24("6789");</code> | <code>(6*8)/(9-7)</code> |
<code>(1+7)*(2+1)</code> | <code>solve24("1127");</code> | <code>(1+7)*(2+1)</code> |
