mkamranhamid / codility-frog-jump.js

Created June 5, 2020 13:34

Count minimal number of jumps from position X to Y.

	// codility test prep questions
	// A small frog wants to get to the other side of the road. The frog is currently located at position X
	// and wants to get to a position greater than or equal to Y. The small frog always jumps a fixed distance, D.
	// Count the minimal number of jumps that the small frog must perform to reach its target.
	// Given X = 10, Y = 85, D = 30
	// the function should return 3

	function numberOfFrogJumps(x,y,d){
	var distanceRequired = y-x;
	var jumps = Math.ceil(distanceRequired/30)

mkamranhamid / codility-array-pair.js

Created June 5, 2020 13:14

Find value that occurs in odd number of elements.

	// codility test prep questions
	// For example, in array A such that:
	// A[0] = 9 A[1] = 3 A[2] = 9 A[3] = 3 A[4] = 9 A[5] = 7 A[6] = 9
	// the elements at indexes 0, 2 and 4 have value 9,
	// the elements at indexes 1 and 3 have value 3,
	// the element at index 5 has value 7 and is unpaired.

	function findPairs(arr){
	var hash = {}
	arr.map((num)=>{

mkamranhamid / codility-sequence.js

Created June 5, 2020 12:59

Find longest sequence of zeros in binary representation of an integer.

	// codility test prep questions
	// For example, number 9 has binary representation 1001 and contains a binary gap of length 2.
	// The number 529 has binary representation 1000010001 and contains two binary gaps: one of length
	// 4 and one of length 3. The number 20 has binary representation 10100 and contains one binary gap of length 1.
	// The number 15 has binary representation 1111 and has no binary gaps. The number 32 has binary representation
	// 100000 and has no binary gaps.

	function findFirstNumberOfZeroes(num){
	var binary = num.toString(2);
	var numberOfZeros = 0;

mkamranhamid / mergeArray.js

Created November 3, 2019 13:47

this problem covers the basic understanding of how we can merge the two arrays if there values overlaps

	// Input: [[1,3],[2,6],[8,10],[15,18]];
	// Output: [[1,6],[8,10],[15,18]];
	// Explaination: Since intervals [1,3] and [2, 6] overlaps, merge them into [1, 6].

	var arr = [[1,3],[2,6],[8,10],[15,18]];
	var newArr = [];
	var index = 0;
	while (index <= arr.length-1) {
	var currentVal = arr[index];
	var nextVal = arr[index+1] \|\| 0;

mkamranhamid / findKthLargestNumber.py

Last active December 15, 2019 09:37

a function to get the K'th largest value in python

	# For an unsorted array/list of n integers find the k-th largest element, where k <= n-1.
	# Example: For A = [5,9,27,3,28,18,45] and k=4 the output will be 18.

	def findKthLargestNumber(arr, n=3):
	k= n-1 #
	print(arr) # previous state
	arr.sort(reverse=True) # {reverse=True} will make the sort to work in descending order
	print(arr) # after sort in descending order
	print(arr[k]) # fetch the kth value
	findKthLargestNumber([5,9,27,3,28,18,45] ,4)
