text: If this is a 0 sum subarray , then compare it with maximum size subarray calculated so far
code: if ( sum == 0 && maxsize < j - i + 1 ) { maxsize = j - i + 1 ; startindex = i ; } } } if ( maxsize == -1 ) printf ( " No ▁ such ▁ subarray " ) ; else printf ( " % d ▁ to ▁ % d " , startindex , startindex + maxsize - 1 ) ; return maxsize ; }
