Challenge #15: ↔️ Autonomous robot

We are developing autonomous robots, called giftbots 🤖🎁, to navigate gift warehouses. The task is to create a function that takes the warehouse 🏬 layout and a series of movements ↔️ as inputs.

The warehouse is represented as an array of text strings, where:

• . indicates a clear path.
• * represents an obstacle.
• ! marks the initial position of the robot.

The movements are provided as an array of text strings, where:

• R moves the robot one position to the right.
• L moves the robot one position to the left.
• U moves the robot one position upwards.
• D moves the robot one position downwards.

The robot cannot pass through obstacles or go beyond the warehouse boundaries.

Function Signature

function autonomousDrive(store, movements) {
  // Function implementation
}

Examples

const store = ['..!....', '...*.*.']

const movements = ['R', 'R', 'D', 'L']
const result = autonomousDrive(store, movements)
console.log(result)
/*
[
  ".......",
  "...*!*."
]
*/

// The last movement is to the left, but it cannot move because there is an obstacle.

Keep in mind that the store is an array that can have a number of rows ranging from 1 to 100, as we have warehouses of all sizes.

Also note that the robot might end up in its initial position if it can't move or if it's going around in circles.
