Given two integers dividend and divisor, write a programme in python that return the quotient after dividing the dividend by the divisor without using multiplication, division, and mod operator. The integer division should truncate toward zero, which means losing its fractional part $($for example, $8\mathrm{.}345$ would be truncated to $8,$ and $-2\mathrm{.}7335$ would be truncated to $-2).$ For an input of dividend $=10$ and divisor $=3,$ the output is $3$ because $10/3=3\mathrm{.}3333$ which is truncated to $3.$ Also, for dividend $=7$ and divisor $=-3,$ the output is $-2$ because $7/-3=-2\mathrm{.}333$ which is truncated to $-2.$
