![🎮 DSA Day 2 Variable Sliding Window
Free Fire lo Safe Zone example ni observe chesthe concept easy ga ardham avutundi.
Safe Zone starting lo big ga untundi. Player move avuthunte zone boundary change avuthundi, so situation batti area shrink avuthundi.
Same idea Variable Sliding Window lo kuda.
Example:
nums = [2, 1, 5, 2, 3, 2]
target = 7
Manam sum ≤ 7 unna longest continuous subarray find cheyyali.
Step 1️⃣ Expand ➡️
[2, 1] → sum = 3 ✅
Condition satisfy avtundi, so window ni expand chestham.
Step 2️⃣ Expand ➡️
[2, 1, 5] → sum = 8 ❌
Target cross ayyindi. So ikkada window ni shrink ⬅️ cheyyali.
2 remove → [1, 5] → sum = 6 ✅
Step 3️⃣ Again Expand ➡️
[1, 5, 2] → sum = 8 ❌
Again 1 remove:
[5, 2] → sum = 7 ✅
Step 4️⃣ Continue
[5, 2, 3] → sum = 10 ❌
Shrink → [2, 3] → sum = 5 ✅
Finally:
[2, 3, 2] → sum = 7 ✅
Longest valid window length = 4
🧠 Actual logic:
Condition satisfy → Expand ➡️
Condition break → Shrink ⬅️
Every valid window → Check best answer
👉 Fixed Sliding Window = window size fixed
👉 Variable Sliding Window = window size changes based on condition
🔥 Simple memory:
Expand → Condition break → Shrink → Continue by @genzfishirl](https://s8.imginn.com/819481971_1057038433964296_809724668193671834_n.jpg?t15.5256-10/819481971_1057038433964296_809724668193671834_n.jpg?stp=dst-jpg_e15_p480x480_tt6&_nc_cat=105&ig_cache_key=NDAwMzgxODI4OTcxMjQ2NTE1OQ%3D%3D.3-ccb7-5&ccb=7-5&_nc_sid=58cdad&efg=eyJ2ZW5jb2RlX3RhZyI6IkNMSVBTLnhwaWRzLjY0MC5zZHIudmlkZW9fZGVmYXVsdF9jb3Zlcl9mcmFtZS5DMyJ9&_nc_ohc=-_w8nW10p98Q7kNvwHXlAis&_nc_oc=AdpBifk_WFAcbUimnf3Opgd5Oone41l3yJE633WiJAJxB4hCHSpyG-340isfWaJ4lrape70mZ79TieFPGiVKvpwU&_nc_ad=z-m&_nc_cid=0&_nc_zt=23&_nc_ht=scontent-iad3-2.cdninstagram.com&_nc_gid=jvkbmCJx0UzmKkbJtzwl1A&_nc_ss=7a20f&oh=00_AQO4I2AxvebD7DrYAf-mqtuj-qLN5pdgiIDvCoYc-5dcwQ&oe=6ADB2FD9)
