Applied Materials Interview Questions and Answers

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is the force applied to a material per unit area

• Strain is the measure of deformation or change in shape of a material

• Stress and strain are related by the material's modulus of elasticity

• Example: When a rubber band is stretched, it experiences stress which causes strain in the form of elongation

Debugging bubble sort involves identifying and fixing errors in the sorting algorithm for arrays.

• Check the outer loop: Ensure it runs for the correct number of passes. Example: for (int i = 0; i < n-1; i++)

• Verify the inner loop: It should compare adjacent elements and swap them if they are in the wrong order. Example: if (arr[j] > arr[j+1])

• Ensure the swap logic is correct: Use a temporary variable to hold one of ...read more

Shared memory is a memory space that multiple processes can access and use to communicate with each other.
