| Problem | Difficulty | Frequency | Topics | |
|---|---|---|---|---|
Unique Binary Search Trees Given an integer n, return the number of structurally unique BST's (binary search trees) which has exactly n nodes of unique values from 1 to n. | Medium | Very Likely | mathdynamic-programmingtree | Solve |
Bricks Falling When Hit You are given an m x n binary grid, where each 1 represents a brick and 0 represents an empty space. A brick is stable if: | Hard | Likely | arrayunion-findmatrix | Solve |

Tower Research Capital interviews focus heavily on math, dynamic-programming, tree problems. If you're short on time, these are the categories to prioritize. The problems on this page are sorted by frequency, so start from the top and work your way down.
Beyond solving problems, practice explaining your approach. Tower Research Capital interviewers care about your thought process - how you break down a problem, consider edge cases, and evaluate tradeoffs between solutions. A clean O(n) solution you can explain clearly beats an O(log n) solution you can't articulate.
