Trying all possibilities in java
<p>I have 4 ints (a,b,c,d) and 3 Strings that represent mathematical operators (+,-,*,/).
I want to check if it's possible to make a certain number (e) from these ints and Strings.</p>

<p>for example:</p>

<p>a + b * c - d == e;</p>

<p>The ints can be used only once each, and the operators can be used multiple times, but only once between every 2 ints. </p>

<p>Can anyone help me?</p>
