and return the new length.
do not allocate extra space for another array, you must do this in place with constant memory.
for example, given input array a = [1,1,2] ,
your function should return length = 2, and a is now [1,2] .
my method：
/*
and return the new length.
do not allocate extra space for another array, you must do this in place with constant memory.
for example, given input array a = [1,1,2] ,
your function should return length = 2, and a is now [1,2] .
*/#include#includevoid main()
; //陣列樣式
int len = sizeof(a)/sizeof(a[0]); //len為陣列長度
int stc_len = len;
int temp;
for (int i = 0; i < len - 1; i++) }
printf("陣列的長度為%d\n", stc_len);
for (int i = 0; i < stc_len; i++)
printf("%d ", a[i]);
printf("\n");
system("pause");
}
the reference：
/*

for example, given input array a = [1,1,2] ,
your function should return length = 2, and a is now [1,2] .
*/#include#includevoid main()
; //陣列樣式
int len = sizeof(a)/sizeof(a[0]); //len為陣列長度
int index = 0;
for (int i = 1; i < len; i++)
index++;
for (int i = 0; i < index; i++)
printf("%d ", a[i]);
system("pause");
}
執行結果：
陣列的長度為2
1 2
請按任意鍵繼續. . .
思考？？？
對於無序的陣列應該這麼做呢？？？

一道筆試題
上次去筆試的時候，有一道題，怎麼也沒做出來，當時也是很緊張，有些思路，但卻沒有做出來。有四個人要過乙個獨木橋，因為天比較黑，而且橋只能允許兩個人同時通過，並且他們只有乙個手電筒。四個人單獨同時橋的時間是1，2，5，8分鐘。問最短的時間是多少？當時我的答案 1和8，1回來，1 5，1回來，1 2 8 ...
