-  3. keep finding the ma profit 
-  4. Tadaaa Done
+  1. Initialize a variable to store the maximum profit (maxProfit) and set it to 0.
+  2. Initialize a variable to store the minimum price seen so far (minPrice) and set it to the first price in the array.
+  3. Iterate through the prices array starting from the second price.
+  4. For each price, update the minPrice if the current price is lower than the minPrice.
+  5. Calculate the profit if the current price is sold at minPrice, and update maxProfit if the calculated profit is greater than maxProfit.
