Simple Binary Search  The my_binary function will find the value named key and check if the key value is in the array list or not.The function will return -1 if the key value is not in the array list else it will return the position of the element in the array list int my_binary(int ara[], int lo, int hi, int key, int siz) {     if(hi>=lo)     {         int mid = lo + (hi-lo)/2;         if(ara[mid]==key)             return mid;         if(key>ara[mid])             return my_binary(ara,mid+1,hi,key,siz);         else             return my_binary(ara,lo,mid-1,key,siz);     }     return -1;       } int my_lower_binary(int ara[], int lo, int hi, int key, int siz) {     if(hi>=lo)     {         int mid = lo + (hi-lo)/2;         if((mid==0 || key>ara[mid-1]) && ara[mid]==key)             return mid;         else if(key>ara[mid])             return my_lower_binary(ara,mid+1,hi,key,siz);         else
