If this is a 0 sum subarray , then compare it with maximum size subarray calculated so far
if ( sum == 0 and maxsize < j - i + 1 ) : NEW_LINE INDENT maxsize = j - i + 1 NEW_LINE startindex = i NEW_LINE DEDENT if ( maxsize == - 1 ) : NEW_LINE print ( " No ▁ such ▁ subarray " ) ; NEW_LINE else : NEW_LINE print ( startindex , " to " , startindex + maxsize - 1 ) ; NEW_LINE return maxsize NEW_LINE
