title: Logic for Nine to one equals 100
body: <p>I was recently asked this question in an interview . Can anyone help me with a code to solve this problem?</p>
  
  <p>We have a sequence of non-zero digits 123456789. The problem is to place plus or minus signs between them so that the result of thus described arithmetic operation will be 100. We can use a number only once . However we can use the operators(+,-,*,/) any number of times</p>
  
  <p>Edit : I was asked to write a Java code for this question . So i believe its relevant</p>
  
  <p>The followup question was to get all possible combinations</p>
