Its quite simple to analyse ...

LOOP i=0: i=0
then enters loop j=o: but it false that always J>100-i;

i.e.., i=0;j=100; 100- i-> 100
so always 100 is not greater than 100

than it comes out no sum++;
Loop i=1; ; j =100 only now 100 - i =99 so j>100 -i
(100>99)
then sum++ is executed ;


i= 1 j=100 j > 100 - i j=99 ;sum ++
i=2 j =99 j> 100 - i j =98 ; sum ++

i=50 j=51 j>100-50 true ( 51>50 ) ; sum++ j=50
i=51 j= 50 j>100-51 true(50>49 ) so no sum++


i = 99 j=2 j>100-i true (2>1) sum ++

so sum++ would be executed 99 times
