We are required to write a function that takes in a one-dimensional array as the first argument and a number n as the second argument and we have to make n subarrays inside of the parent array (**if possible) and divide elements into them accordingly.** if the array contains 9 elements and we asked to make 4 subarrays, then dividing 2 elements in each subarray creates 5 subarrays and 3 in each creates 3, so in such cases we have to fallback to nearest lowest level (3 in this case) because our requirement is to distribute equal number of elements ...

We are required to write a function, say isPowerOfTwo() that takes in a positive number and returns a boolean based on the fact whether or not the number is some power of 2.For example −console.log(isPowerOfTwo(3)); //false console.log(isPowerOfTwo(32)); //true console.log(isPowerOfTwo(2048)); //true console.log(isPowerOfTwo(256)); //true console.log(isPowerOfTwo(22)); //falseLet’s write the code for this function, it will be a very straightforward recursive function that keeps recurring until the number stays divisible by 2, if in this process the number gets reduced all the way down to 1, it is a power of 2 otherwise it isn’t. Here is the code −Exampleconst isPowerOfTwo = num => ... Read More
Let’s say, we are required to write a function classifyArray() that takes in an array which contains mixed data types and returns a Map() with the elements grouped by their data types.For example −// if the input array is: const arr = ['class', 2, [7, 8, 9], {"name": "Michael"}, Symbol('foo'), true, false, 'name', 6]; // then the output Map should be: Map(5) { 'string' => [ 'class', 'name' ], 'number' => [ 2, 6 ], 'object' => [ [ 7, 8, 9 ], { name: 'Michael' } ], 'symbol' => [ Symbol(foo) ], 'boolean' => ...

We are required to write a function that does the following transformation −If the input object is −const input = { a: 0, b: {x: {y: 1, z: 2}}, c: 3 };Then the output of the function should be −const output = { a: 0, 'b.x.y': 1, 'b.x.z': 2, c: 3 }We basically have to write a function that flattens a nested object. Will do this via recursion and the code for doing this will be −Exampleconst obj = { a: 1, b: {x: {y: 1, z: 2}}, c: 3 ... Read More
Let’s say, we are required to write a function, say parseEqualInterval() that takes in an array of Numbers of strictly two elements as the first argument and a number n as the second argument and it inserts n-1 equidistant entries between the actual two elements of the original array so that it gets divided into n equal intervals.For example −// if the input array is const arr = [12, 48]; // and the interval is 4 //then the output array should be: const output = [12, 21, 30, 39, 48];This way the array got divided into 4 equal intervals. So, ... Read More
Let’s say, we are required to write a function, say isSame() that accepts a nested object and returns a boolean depending on the fact whether or not all the keys have the same values. When saying all the keys we mean all the last keys like if a key has a nested object as its value, we are required to traverse to the end of the nested object and check for that value.For example − If the object is −const obj = { a: 1, b: 1, c: { aa: 1 } };Then ...

We are required to write a function, say minMax() that takes in an array of Numbers and rearranges the elements such that the greatest element appears first followed by the smallest elements then the second greatest element followed by second smallest element and so on.For example −// if the input array is: const input = [1, 2, 3, 4, 5, 6, 7] // then the output should be: const output = [7, 1, 6, 2, 5, 3, 4]So, let’s write the complete code for this function −Exampleconst input = [1, 2, 3, 4, 5, 6, 7]; const minMax = arr ...

Consider we have an array of Numbers that looks like this −const array = [3.1, 1, 2.2, 5.1, 6, 7.3, 2.1, 9];We are required to write a function that counts how many of the elements are in the array below / above a given number.For example, if the number is 5.25, the answer should be the following 5 elements, (3.1, 1, 2.2, 5.1, 2.1)and 3 elements above it −(6, 7.3, 9)Note − If any element is equal to the provided number, it should be counted as above the number.So, let’s write the code for this function −Exampleconst array = [3.1, ...

To remove windows features, we can use command Remove-WindowsFeature command is used along with feature name.Remove-WindowsFeature Search-Service -VerboseVERBOSE: Uninstallation started... VERBOSE: Continue with removal? VERBOSE: Prerequisite processing started... VERBOSE: Prerequisite processing succeeded. Success Restart Needed Exit Code Feature Result ------- -------------- --------- -------------- True No Success {Windows Search Service} VERBOSE: Uninstallation succeeded.If the windows feature has the management tools like as in Web-Server (IIS) feature, you can add the same in the command line. If the server requires restart then you can add the -Restart parameter. For example, Remove-WindowsFeature Web-Server -IncludeManagementTools -Restart -VerboseIf we check the -Name parameter, it supports ... Read More
