Question

Python , no strings, len(), or indexing

Write the function setKthDigit(n, k, d) that takes three
# non-negative integers -- n, k, and d -- where d is a single digit
# (between 0 and 9 inclusive), and returns the number n but with
# the kth digit replaced with d. Counting starts at 0 and goes
# right-to-left, so the 0th digit is the rightmost digit.

def setKthDigit(n, k, d):
    n1 = n // (10 ** (k + 1))
    n2 = n % (10 ** (k))

    n = n1 * (10 ** (k + 1)) + d * (10 ** (k)) + n2

    return n


print(setKthDigit(123456789, 0, 0))
print(setKthDigit(123456789, 1, 0))
print(setKthDigit(123456789, 2, 0))
print(setKthDigit(123456789, 3, 0))
print(setKthDigit(123456789, 4, 0))
print(setKthDigit(123456789, 6, 0))
print(setKthDigit(123456789, 7, 0))
