Understanding the Calculate Score After Performing Instructions Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given two arrays, instructions and values, both of size n. You need to simulate a process based on the following rules: You start at the first instruction at index i = 0 with an initial score of 0. If instructions[i] is "add": Add values[i] to your score. Move to the next instruction (i + 1). If instructions[i] is "jump": Move to the instruction at index (i + values[i]) without modifying your score. The process ends when you either: Go out of bounds (i.e., i < 0 or i >= n), or Attempt to revisit an instruction that has been previously executed. The revisited instruction is not executed. Return your score at the end of the process.

Examples
instructions = ["jump","add","add","jump","add","jump"], values = [2,1,3,1,-2,-3]1Simulate the process starting at instruction 0: At index 0: Instruction is "jump", move to index 0 + 2 = 2. At index 2: Instruction is "add", add values[2] = 3 to your score and move to index 3. Your score becomes 3. At index 3: Instruction is "jump", move to index 3 + 1 = 4. At index 4: Instruction is "add", add values[4] = -2 to your score and move to index 5. Your score becomes 1. At index 5: Instruction is "jump", move to index 5 + (-3) = 2. At index 2: Already visited. The process ends.
instructions = ["jump","add","add"], values = [3,1,1]0Simulate the process starting at instruction 0: At index 0: Instruction is "jump", move to index 0 + 3 = 3. At index 3: Out of bounds. The process ends.
instructions = ["jump"], values = [0]0Simulate the process starting at instruction 0: At index 0: Instruction is "jump", move to index 0 + 0 = 0. At index 0: Already visited. The process ends.
