Questions 1

Consider the program below.
• Fill in the blank at LINE-1 to declare a stack variable s.
• Fill in the blank at LINE-2 to push value into stack.
• Fill in the blank at LINE-3 with appropriate statement.
The program must satisfy the given test cases.

Solution:

stack<char> s;//LINE-1
for(int i=0;i<strlen(str);i++)
s.push(str[i]); //LINE-2
for(int i=0;i<strlen(str)-1;i++){
ch = s.top(); //LINE-3

Question 3

Consider the program below.
• Fill in the blank at LINE-1 to include the appropriate header file to utilize abs(·) function.
• Fill in the blank at LINE-2 to compute the length between two points p1 and p2 as
|(p1.y − p2.y)| + |(p1.x − p2.x)|.
The program must satisfy the given test cases.

Solution:

#include <iostream>
#include <cmath>     //LINE-1 
using namespace std;
struct point{
    int x, y;
};
double get_len(point p1, point p2){
    return abs(p1.y - p2.y) + abs(p1.x - p2.x);    //LINE-2
}
