In this simple assignment you are given a number and have to make it negative. But maybe the number is already negative? Examples makeNegative(1); // return -1 makeNegative(-5); // return -5 makeNegative(0); // return 0 makeNegative(0.12); // return -0.12 Notes The number can be negative already, in which case no change is required. Zero (0) is not checked for any specific sign. Negative zeros m..

Your function takes two arguments: current father's age (years) current age of his son (years) Сalculate how many years ago the father was twice as old as his son (or in how many years he will be twice as old). The answer is always greater or equal to 0, no matter if it was in the past or it is in the future. Solution: def twice_as_old(dad_years_old, son_years_old): return abs(dad_years_old - so..

In this simple exercise, you will create a program that will take two lists of integers, a and b. Each list will consist of 3 positive integers above 0, representing the dimensions of cuboids a and b. You must find the difference of the cuboids' volumes regardless of which is bigger. For example, if the parameters passed are ([2, 2, 3], [5, 4, 1]), the volume of a is 12 and the volume of b is 20..

Given the following table 'decimals': decimals table schema id number1 number2 Return a table with two columns (abs, log) where the values in abs are the absolute values of number1 and the values in log are values from number2 in logarithm to base 64. Solution: SELECT ABS(number1), LOG(64, number2) FROM decimals Result: abs log 2849.529276973034 0.5513855124091469e1 168.16728863472508 0.53183827..

Description: Given a variable n, If n is an integer, Return a string with dash'-'marks before and after each odd integer, but do not begin or end the string with a dash mark. If n is negative, then the negative sign should be removed. If n is not an integer, return an empty value. Ex: dashatize(274) -> '2-7-4' dashatize(6815) -> '68-1-5' Solution: 1. If 'n' is not a number, 'None' is returned. 2..

Description: You are given two arrays a1 and a2 of strings. Each string is composed with letters from a to z. Let x be any string in the first array and y be any string in the second array. Find max(abs(length(x) − length(y))) If a1 and/or a2 are empty return -1 in each language except in Haskell (F#) where you will return Nothing (None). Example: a1 = ["hoqq", "bbllkw", "oox", "ejjuyyy", "plmii..
