We are required to write a JavaScript function that takes in a bunch of numbers and returns the correct sequence of operations to satisfy the equation. The operator that can be used are (+, −, *, /, ^, %).For example −Input : 5 3 8 ... Read More

Suppose, we have two arrays of numbers that represents two ranges like these −const arr1 = [2, 5]; const arr2 = [4, 7];We are required to write a JavaScript function that takes in two such arrays.The function should then create a new array of range, that is the intersection of ... Read More

We are required to write a JavaScript function that takes in an array of literals that have repeating values. Our function should return an array of the most common element(s) in the array (if two or more elements appear for the same number of most times then the array should ... Read More

Suppose we have an array of objects like this −const arr = [    {_id : "1", S : "2"},    {_id : "1", M : "4"},    {_id : "2", M : "1"},    {_id : "" , M : "1"},    {_id : "3", S : "3"} ];We ... Read More

Suppose, we have two objects like these −const obj1 = {    positive: ['happy', 'excited', 'joyful'],    negative: ['depressed', 'sad', 'unhappy'] }; const obj2 = {    happy: 6,    excited: 1,    unhappy: 3 };We are required to write a JavaScript function that takes in two such objects. The ... Read More

Given an array of five positive integers, we are required to find the minimum and maximum values that can be calculated by summing exactly four of the five integers.Then print the respective minimum and maximum values as a single line of two spaceseparated long integers.The array is not sorted all ...

Suppose, we have a long string that represents a number like this −const str = '11222233344444445666';We are required to write a JavaScript function that takes in one such string. Our function is supposed to return an object that should assign a unique "id" property to each unique number in the ... Read More

We are required to write a JavaScript function that takes in an array of sorted integers and a target average as first and second arguments.The function should determine whether there is a pair of values in the array where the average of the pair equals to the target average.There's a ...

Suppose, we have an array of arrays like this −const arr = [[12345, "product", "10"], [12345, "product", "15"], [1234567, "other", "10"]];We are supposed to write a function that takes in one such array. Notice that all the subarrays have precisely three elements in them.Our function should filter out that subarray ... Read More
