Minimum Moves to Equal Array Elements II
A medium-tier problem at 61% community acceptance, tagged with Array, Math, Sorting. Reported in interviews at Myntra and 1 others.
Minimum Moves to Equal Array Elements II is a medium difficulty array problem that's asked at companies like Myntra and TCS. The problem asks you to make all elements equal by incrementing or decrementing them, minimizing total moves. It's a deceptively simple premise that catches candidates off guard because the greedy intuition doesn't work and sorting isn't just for convenience. With a 61% acceptance rate, most people get partway through before hitting a wall on the math. If this problem shows up on your live assessment and you blank on why the median matters, StealthCoder surfaces the solution invisibly while you stay calm.

Minimum Moves to Equal Array Elements II is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by an Amazon engineer who used it to pass JPMorgan's OA and system design loop.
Get StealthCoderThe trick here is recognizing this is a median problem, not a mean or greedy problem. Most candidates think 'make everything equal to the average', but that's not optimal for a move-counting problem with free-directional increments and decrements. The optimal target is always the median of the array. Once you sort, the median minimizes the sum of absolute differences. The common pitfall is overthinking it as a simulation or trying to calculate moves greedily without ever sorting. Another miss: confusing this with problems that need a specific element value. You don't pick a target value from the array, you compute the actual median after sorting. The algorithm is sort, find median, compute sum of absolute differences. If you haven't drilled median-based optimization or blank under pressure during screen share, StealthCoder runs invisibly and returns a working solution in seconds.

Minimum Moves to Equal Array Elements II interview FAQ
Why can't I just increment or decrement everything to the mean?+
The mean minimizes squared differences, not absolute differences. This problem counts individual moves, so sum of absolute deviations is what matters. The median always minimizes sum of absolute deviations. Two companies have asked this, and both expect the median approach, not mean-based solutions.
Is the optimal target always in the original array?+
No. The median might not exist as an element. For even-length arrays, any value between the two middle elements is equally optimal. For odd-length arrays, the middle element is the target. Don't assume the target must be an existing value.
How does sorting relate to the solution?+
Sorting lets you instantly find the median in O(n log n) time. Without sorting, finding median is harder. Once sorted, median is array[n/2] for even n or array[n/2] for odd n, depending on implementation. Sorting is mandatory, not optional.
Will this problem stay easy if I see the median hint first?+
Yes, but only if you implement cleanly. The code is short once you know median is the target. But under live pressure without the hint, most candidates spend time trying other approaches first. That's where blanking happens and the safety net matters.
Is this still asked at FAANG-tier companies like Myntra and TCS?+
Both Myntra and TCS have reported asking it. It's less common at pure FAANG, but medium-tier tech companies use it as a quick filter for whether you know the median trick. Acceptance is 61%, so not everyone nails it on first try.
