Question
Function printRanges(7, 3) produces the following output: 7 0 1 2 3 4 5 6 6 0 1 2 3 4 5 5 0 1 2 3 4 4 0 1 2 3 3 0 1 2 Write function printRanges(high, low) that produces output according to the rule implied by the example output. You may assume high and low are positive integers with high >= low. You function *must* contain two loops, one nested within the other. Your function may not use any comprehensions, string operations, range, or list functions; the goal is to practice loops and incrementing. FOR PYTHON
Explanation / Answer
# As range is not allowed we use while loop and
# increment/decrement loop counter ourself
def printRanges(high, low):
# This loop variable is use to control numbers printed on same line
i = high
# we decrement i in each loop to print number from 0 to i
# outer loop print for each i until it is same as low
while i >= low:
j = 0
print i
# inner loop print number from 0 to i. ',' after print
# is required so that things are printed on same line
while j < i:
print j,
j = j + 1
print ""
i = i - 1
