I did in a different way let outPut = []; let skillMap = {}; for (let char of endorsements) { if (char['skill'] in skillMap) { skillMap[char['skill']] = [...skillMap[char['skill']], char['user']]; } else { skillMap[char['skill']] = [char['user']]; } } for (let key in skillMap) { let skillObj = {}; skillObj['skill'] = key; skillObj['user'] = skillMap[key]; skillObj['count'] = skillMap[key].length; outPut.push(skillObj); } return outPut.sort((a, b) => b.count - a.count); Minder

getSkills = endorsements => { const skillMap = {}; // assumption - each object has all the properties, nothing is missing endorsements.forEach((item, index) => { const { skill, user } = item; if (!skillMap[skill]) { skillMap[skill] = {}; skillMap[skill]["user"] = []; // skillMap[skill]["user"].push(user); skillMap[skill]["count"] = 0; } skillMap[skill]["user"].push(user); skillMap[skill]["count"] += 1; // } }); return Object.keys(skillMap).map(key => [ { skill: key, ...skillMap[key] } ]); }; Minder

"It's always revenue my man/woman." I hope you understand how irrelevant you observation is in the context of this position. So no, it's not "always revenue." Minder

Did they request to do a background screening on you before rejecting?

udaykanth, I would say that a .forEach() would be the most common and most basic use of a callback function. I'm just writing this to help anyone that might have a hard time thinking up a quick example if the come across this question themselves. Example: var numArray = [ 1, 2, 3 ] ; numArray.forEach( function( i ) { console.log( arr[ i - 1 ] ) } ) ; // logs out // 1 // 2 // 3 Minder

I don't think Bloomberg is a very good company. I am an excellent web developer and have gotten multiple offers from other companies with big names, but was rejected by Bloomberg. They are too demanding during the job interview and it becomes a game of how well you can interview as opposed to how talented an employee you are and how much you can contribute to the growth of the company.

you can add oncl1ck event to assign event target value to a variable for each fieldset, since there are 3 different field sets, and we want to know each of them separately. Minder

store each row as a decimal for ex: if the row is 1011 -> store it as 13!

Since all values are mod 2 you can pack 64 entries together into on int64_t. You can then add two matrices by XORing each entry. Minder

A better asnwer is to do it in-place with pointers. O(N) speed and O(N) space. function checkPalindrome(i, input){ var leftPointer = 0; var rightPointer = 0; if(i===0){ //base case of single char return true; } var odd = (i+1)%2; //we know it's not 0 if(odd){ leftPointer = i/2; //not 0 rightPointer = i/2; //not 0 while(input[leftPointer] === input[rightPointer] && leftPointer > 0 && rightPointer 0 && rightPointer < input.length){ leftPointer = leftPointer - 1; rightPointer = rightPointer + 1; } } if(input[leftPointer] === input[rightPointer] && leftPointer === 0){ return true; }else{ return false; } } var improvedMinPalindromeAddition = function(input){ var inputArray = input.split(""); //max string size is greater then max array size(4.29 billion elements)..we could also do it inline w/string manipulation var largestPalindrome = 0; for(var i=0;i Minder
