Topic:Suppose an ordered array rotates at a certain position, and a new array is rotated, which is an ordered array of rotations. such as: (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).Now given an array of these, look for a number in the array.

Most programs in the C + + language cannot be separated from pointers and arrays, so we need to figure out pointers and arrays.First, set a character array char s[10]; then define a pointer to a character char* p; The array is declared with [],
