- (Array.length-1)/ 2 and Array.length/2 取中值 index
Array.length is even * * * * * * ^ (Array.length-1)/2 * * * * * * ^ Array.length/2 当Array.length is even, -1 对中值index有影响 Array.length is odd * * * * * ^ (Array.length-1)/2 == Array.length/2 当Array.length is odd, -1 对中值index无影响 example: 1: reverse Array for(int i=0;i<array.length/2;++i){ int tmp=array[array.length-1-i]; array[array.length-1-i]=array[i]; array[i]=tmp; }
