This is the solution to the Modified Kaprekar Numbers found in the implementation section of the algorithm domain in Hackerrank. A modified Kaprekar number is a positive whole number n with d digits, such that when we split its square into two pieces – a right hand piece r with d digits and a left hand piece l that contains the remaining d or d−1 digits, the sum of the pieces is equal to the original number (i.e. l + r = n).

The Code
def sendKap(x, s): y = x * x y = str(y) s1 = y[: len(y) / 2: ] s2 = y[len(y) / 2::] s3 = int(s1) + int(s2) if (s3 == x): s.append(str(x)) st = input() en = input() s = [] for i in range(st, en + 1): if (i & gt; 9): sendKap(i, s) elif(i == 1): s.append(str(i)) elif(i == 9): s.append(str(i)) if (len(s) == 0): print 'INVALID RANGE' else : print ' '.join(s) < /pre>
