WebIn line 9, we sort the vector with the built-in sort () function. In line 13, we call the binary_search () function, and then print whether the num is found inside the vector not. In this way, we can use the built-in binary_search () function to avoid the extra time to write the logic from scratch. This helps immensely in coding contests. WebThe inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. Compute guess as the average of max and min, rounded down (so that it is an integer). cs lewis quotes on leadership
