Queue - Explained. A queue is a linear data structure that follows the rule First item added is the first item removed. Think of it like a line at a bus stop. The person who comes first gets on the bus first. New people join at the back. Queue Methods: Enqueue Adds an element to the back of the queue. Dequeue Removes the element from the front. Front or Peek Returns the front element without removing it. IsEmpty Checks if the queue is empty. Size Returns the number of elements. Time Complexity: Enqueue O(1) Dequeue O(1) Peek O(1) Search O(n) Where It’s Used: Task scheduling in operating systems Handling requests in servers Breadth First Search in graphs Printer job management

🔄 Circular Queue vs Linear Queue A Linear Queue follows FIFO but cannot reuse empty spaces, which can waste memory. A Circular Queue connects the end to the beginning, allowing efficient reuse of space. 👉 Linear Queue = Simple but less efficient 👉 Circular Queue = Better memory utilization and performance #DataStructures #Programming #ComputerScience

Heatmaps are a great way to spot patterns in data at a glance. This example uses data in A1:C69 to visualise shop footfall by day and hour: df = xl("A1:C69", headers=True) df["Day"] = pd.Categorical( df["Day"], ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"], ordered=True ) sns.heatmap( df.pivot( index="Day", columns="Hour", values="Customers in shop" ), cmap="RdYlGn_r", annot=True ).set_title("Shop footfall by day and hour") Start by typing =PY( to enter Python mode. Assign the whole data range to a DataFrame called df to make the data available to Python. Next, convert the 'Day' column into a categorical and explicitly define the order from Monday through Sunday. Setting the category as ordered ensures the rows appear in a natural sequence rather than alphabetical order. Reshape the data using a pivot: place 'Day' on the vertical axis, 'Hour' across the bottom, and use 'Customers in shop' as the grid values. Pass this pivoted data into Seaborn’s heatmap function. Apply a reversed red–yellow–green colour map, so red highlights the busiest periods and green the quietest. Switch annotations on to display the values, and finish by setting a clear title. #excel #exceltips #exceleration #globalexcelsummit

🔄 Circular Queue in Data Structures A Circular Queue connects the last position back to the first, forming a circle. This helps reuse empty space and avoids memory wastage. ✅ More efficient than Linear Queue 💻 Used in CPU scheduling, buffering, and real-time systems #CircularQueue #DSA #Java #Programming

Insert Interval | LeetCode 57 | Greedy Pattern Explained Another 🔥 Blind 75 must-know problem! You’re given non-overlapping intervals sorted by start time. Insert a new interval and merge if needed. Sounds easy… but the trick is the 3-phase greedy approach 👇 💡 Strategy: 1️⃣ Add all intervals that end before new interval starts 2️⃣ Merge all overlapping intervals 3️⃣ Add remaining intervals No sorting needed. One pass. Clean logic. ⚡ Time Complexity: O(n) ⚡ Space Complexity: O(n) This pattern appears in: • Calendar booking problems • Meeting rooms • Merge intervals • Scheduling systems Master this and interval problems become EASY. Save this for interviews 📌 Comment “INTERVALS” if you want full interval pattern roadmap next. #leetcode #greedyalgorithm #codinginterview #blind75 #softwareengineer

✅ Solved LeetCode Problem 696 – Count Binary Substrings Today I solved LeetCode 696, a great problem focused on string manipulation and pattern recognition. The task is to count the number of non-empty substrings that have equal numbers of consecutive 0’s and 1’s, and all the 0’s and 1’s in those substrings are grouped consecutively. 🔹 This problem helps improve understanding of: String traversal techniques Counting consecutive characters Optimizing from brute-force to efficient linear solution (O(n)) 💡 The key idea is to track consecutive groups of 0’s and 1’s and count valid pairs based on the minimum of adjacent group lengths. Another step forward in mastering Data Structures & Algorithms 🚀 Consistency is the key! #leetcode #dsa #softwareengineer #programmer #java
