Given an array of integers your solution should find the smallest integer. For example: Given [34, 15, 88, 2] your solution will return 2 Given [34, -345, -1, 100] your solution will return -345 You can assume, for the purpose of this kata, that the supplied array will not be empty. Solution: # 1 def find_smallest_int(arr): return sorted(arr, reverse=True).pop() # 2 def find_smallest_int(arr): r..

Given a 2D ( nested ) list ( array, vector, .. ) of size m * n, your task is to find the sum of the minimum values in each row. For Example: [ [ 1, 2, 3, 4, 5 ] # minimum value of row is 1 , [ 5, 6, 7, 8, 9 ] # minimum value of row is 5 , [ 20, 21, 34, 56, 100 ] # minimum value of row is 20 ] So the function should return 26 because the sum of the minimums is 1 + 5 + 20 = 26. Note: You will alwa..

You are given an odd-length array of integers, in which all of them are the same, except for one single number. Complete the method which accepts such an array, and returns that single different number. The input array will always be valid! (odd-length >= 3) Examples [1, 1, 2] ==> 2 [17, 17, 3, 17, 17, 17, 17] ==> 3 Solution: def stray(arr): import collections return [k for k, v in collections.C..

There is an array with some numbers. All numbers are equal except for one. Try to find it! find_uniq([ 1, 1, 1, 2, 1, 1 ]) == 2 find_uniq([ 0, 0, 0.55, 0, 0 ]) == 0.55 It’s guaranteed that array contains at least 3 numbers. The tests contain some very huge arrays, so think about performance. Solution: def find_uniq(arr): n = arr[0] == arr[-1] and arr[0] or arr[1] return [i for i in arr if n != i..

Given a table of random numbers as follows: numbers table schema id number1 number2 Your job is to return table with similar structure and headings, where if the sum of a column is odd, the column shows the minimum value for that column, and when the sum is even, it shows the max value. You must use a case statement. output table schema number1 number2 Solution: SELECT CASE WHEN MOD(SUM(number1)..

or this challenge you need to create a simple MIN / MAX statement that will return the Minimum and Maximum ages out of all the people. people table schema id name age select table schema age_min (minimum of ages) age_max (maximum of ages) Solution: SELECT MIN(age) AS age_min, MAX(age) AS age_max FROM people Result: age_min age_max 11 99

Description: Simple, given a string of words, return the length of the shortest word(s). String will never be empty and you do not need to account for different data types. Solution: 1. Count the number of letters in each word. 2. Returns the smallest number of characters. def find_short(s): return min(list(map(len, s.split())))

Description: The museum of incredible dull things The museum of incredible dull things wants to get rid of some exhibitions. Miriam, the interior architect, comes up with a plan to remove the most boring exhibitions. She gives them a rating, and then removes the one with the lowest rating. However, just as she finished rating all exhibitions, she's off to an important fair, so she asks you to wr..

Description: Create a function that returns the sum of the two lowest positive numbers given an array of minimum 4 positive integers. No floats or non-positive integers will be passed. For example, when an array is passed like [19, 5, 42, 2, 77], the output should be 7. [10, 343445353, 3453445, 3453545353453] should return 3453455. Solution: 1. Find the two smallest numbers. 2. Returns the sum o..

Description: In this little assignment you are given a string of space separated numbers, and have to return the highest and lowest number. Examples highAndLow("1 2 3 4 5"); // return "5 1" highAndLow("1 2 -3 4 5"); // return "5 -3" highAndLow("1 9 3 4 -5"); // return "9 -5" Notes All numbers are valid Int32, no need to validate them. There will always be at least one number in the input string...
