复制LED上的按钮顺序

Question

我正在从事一个项目，该项目保证在LED上运行按钮序列（以及时序）。当按下第一个按钮时，arduino开始读取第二个按钮的状态。存储第二个按钮上的按下顺序，直到再次按下第一个按钮。现在，已存储的按钮序列将复制到LED上。我想出了一个代码，该代码尝试执行除LED部分以外的基本功能。但我没有得到想要的输出。你们能帮我检查一下吗？

#include <Debounce.h>






const byte SWITCH = 2;
const byte SWITCH1 = 4;
const byte LED = 9;
int count = 0;
unsigned long startTime = 0;
unsigned long endTime = 0;
unsigned long startTime1 = 0;
unsigned long endTime1 = 0;
unsigned long elapsedTime = 0;
unsigned long elapsedTime1 = 0;
const byte debounceDelayTime = 50;

int a[100],i,j,flag = 0,flag1 = 0,b=0;

Debounce debouncer = Debounce(debounceDelayTime, SWITCH);

void setup(){
  Serial.begin(9600);
  pinMode(SWITCH, INPUT_PULLUP);
  pinMode(SWITCH1, INPUT_PULLUP);
  pinMode(LED, OUTPUT);

              {
                startTime = millis();
