java - Multiple inputs and getting output at once -

i intend find number of palindromes inbetween given numbers, variable 't' decides number of test cases. example, if t=2 give input :

2 12 23(in next line) 56 78(in next line) output be: 1 2 (next line) 

but code after input given :

2 12 23  

i output 1 , should proceed give next test case

how can give both test cases once?
