Divide two integers in leetcode python with some catches.
Given two integers
dividendanddivisor, divide two integers without using multiplication, division, and mod operator.The integer division should truncate toward zero, which means losing its fractional part. For example,
8.345would be truncated to8, and-2.7335would be truncated to-2.Return the quotient after dividing
dividendbydivisor.Note: Assume we are dealing with an environment that could only store integers within the 32-bit signed integer range:
[−231, 231 − 1]. For this problem, if the quotient is strictly greater than231 - 1, then return231 - 1, and if the quotient is strictly less than-231, then return-231.
- I had to abs value both dividend and divisor at the start, also keep a variable valued at 0.
- So we had to create a while loop, if divident was greater than = divisor we minus d - dv and add 1 to output.
- This code checks whether one of the dividend or divisor is negative. If so, it makes the output negative to ensure the correct sign of the division result.
class Solution(object):
def divide(self, dividend, divisor):
d = abs(dividend)
dv = abs(divisor)
output = 0
while d >= dv:
d -= dv
output += 1
if (dividend < 0 and divisor >= 0) or (divisor < 0 and dividend >= 0):
output = -output
return output
