    Python 3 solution:

    import decimal
n=int(input().strip())
p=int(input().strip())
decimal.getcontext().prec=p+4
total=0
for i in range(2,n+1):
    if int(i**0.5)!=i**0.5:
        digits=list(str(decimal.Decimal(i).sqrt()))[:p+1]
        digits.remove('.')
        #print(len(digits))
        total+=sum(map(int,digits))
print(total)
