Round by round

1. 1

   Data Structures and Algorithms Round 160 min

   Q1: Given an array of integers, check if it contains any duplicates. Return true if any value appears more than once, otherwise return false. Q2: You’re given a list of [student, subject, marks]. You need to

   • Group marks by student
   • For each student, compute their highest subject marks
   • Return the student with the highest of these values (means overall topper)
   • Contains any Duplicates
2. 2

   DSA Round 260 min

   Asked 2 DSA easy to medium problems

   • K-th Largest element in an array
   • Find minimum in Rotated Sorted Array
3. 3

   Technical Interview (Frontend)60 min

   Contrast map, filter, reduce and reduceRight

   • When would reduceRight change results?
   • Rest vs Spread: collecting params vs cloning/merging.

   Flatten a array and deduplicate while preserving order using only reduce (no flat, no Set in the return) Input: [[1,2],[2,3,1],[4,3]] Output: [1,2,3,4].

   You have orders: [{ user, status, items:[{ price, qty, inStock }], coupon?: { type:"flat"|"percent", value } }] Using filter + reduce

   • Include only status === completed.
   • Sum price*qty for inStock items, then apply coupon per order.
   • Return the top 2 users by total spend, descending.
