1. Two Sum
Find two indices that add to a target. Juniper uses this as a first-round filter to check whether candidates think in O(n) hash-map terms rather than O(n²) nested loops — the same trade-off that matters when scanning packet headers in fast-path forwarding code.

70. Climbing Stairs
Count distinct ways to climb n stairs taking 1 or 2 steps at a time. Juniper uses this as a gentle DP introduction — the recurrence mirrors hop-count path enumeration in network topology analysis where you want to count distinct routes between two routers with a maximum hop constraint.
