find an available item in array
Dear all,
I'm have a sorted array like this:
177
220
1001
2000
2001
2003
2005
notice that 2002 and 2004 are NOT in array.
Then user input a number INPUT, our script should return OUTPUT value like this:
if INPUT is not in array => OUTPUT=INPUT
if INPUT is in array => OUTPUT is the smallest number that larger than INPUT
and should NOT exist in array!
Example with this array:
INPUT => OUTPUT
1000 => 1000
1001 => 1002
2000 => 2002
2005 => 2006
Can anyone help me to complete this on bash shell!
