Suppose we have a string where we have few integers which are separated by comma. We shall have to separate them out and display each integer in different line. To do this we shall use stringstream (under sstream library) in C++. This is one string based stream class present in C++. We can use extraction operator () to insert something and str() functions to set contents of underlying string device object.So, if the input is like s = "56, 9, 85, 256, 47", then the output will be56 9 85 256 47To solve this, we will follow these steps −Define ...

Suppose we have an array with n different elements. We shall have to reverse the elements present in the array and display them. (Do not print them in reverse order, reverse elements in place).So, if the input is like n = 9 arr = [2, 5, 6, 4, 7, 8, 3, 6, 4], then the output will be [4, 6, 3, 8, 7, 4, 6, 5, 2]To solve this, we will follow these steps −for initialize i := 0, when i < quotient of n/2, update (increase i by 1), do:temp := arr[i]arr[i] := arr[n - i - 1]arr[n - ...

Suppose we have two numbers a and b. We shall have to define a function that can calculate (a + b) and (a - b) both. But using a function in C++, we can return at most one value. To find more than one output, we can use output parameters into function arguments using pointers, and call that function using addresses of those variables. Here in this problem we shall update a with a+b and b with a-b. When we call the function we shall have to pass the address of these two variables.So, if the input is like a ... Read More

Suppose we have four integers a, b, c and d. We shall have to find the greatest number among them by making our own function. So we shall create one max() function that takes two numbers as input and finds the maximum, then using them we shall find maximum of all four numbers.So, if the input is like a = 75, b = 18, c = 25, d = 98, then the output will be 98.To solve this, we will follow these steps −define a function max(), this will take x and yreturn maximum of x and ytake four numbers ...

Suppose we have an array nums, there are at most 50 unique values. We also have another array called quantity, where quantity[i] denotes the amount of values the ith customer ordered.We have to check whether it is possible to distribute nums such thatThe ith customer gets exactly quantity[i] items, The value that the ith customer gets are all equal, andAll customers are satisfied.So, if the input is like nums = [5, 1, 2, 2, 3, 4, 4, 3, 3] quantity = [2, 2, 3], then the output will be True because two customer wants two elements each, so they can ...

Suppose we have two digits a and b. We shall have to convert each digit into words and print them one by one. Printing digits into words means for a digit 5, it should print "Five".So, if the input is like a = 2, b = 6, then the output will beTwo Three Four Five SixTo solve this, we will follow these steps −if d < 0 and d > 9, then:return ("Beyond range of 0 - 9")otherwise when d is same as 0, then:return ("Zero")otherwise when d is same as 1, then:return ("One")otherwise when d is same as 2, ...

Suppose we have a number n, we have to transform it into 0 using the following operations any number of times −Select the rightmost bit in the binary representation of n.Change the ith bit in the binary representation of n when the (i-1)th bit is set to 1 and the (i-2)th through 0th bits are set to 0.So finally we have to find the minimum number of operations required to transform n into 0.So, if the input is like n = 6, then the output will be 4 because initially 6 = "110", then convert it to "010" by second ...

Suppose we have a digit d, we shall have to convert it into words. So if d = 9, our output should be "Nine". If we provide some d which is beyond the range of 0 and 9, it will return appropriate output.So, if the input is like d = 3, then the output will be "Three".To solve this, we will follow these steps −Define a function solve(), this will take d, if d < 0 and d > 9, then:return ("Beyond range of 0 - 9")otherwise when d is same as 0, then:return ("Zero")otherwise when d is same as ...

Suppose, there are n number of hostel rooms numbered from 0 to n-1. The students in the hostel rooms want to transfer to another room, and they place several requests to do that. No hostel seat remains vacant, a transfer request is only taken care of if another student takes the place of the student willing to transfer. So, given the requests, we have to find out how many requests can be satisfied.So, if the input is like n = 3, requests = [[0, 2], [1, 0], [2, 1]], then the output will be 3.The student in room 0 transfers ...

Suppose we have two numbers a and b, a is integer and b is a float. We shall have to take them from standard input and display the sum.So, if the input is like a = 10 b = 56.23, then the output will be Sum: 66.23To solve this, we will follow these steps −To display output into the standard output device we can use extraction operator ()ExampleLet us see the following implementation to get better understanding −#include using namespace std; int main(){    int a;    float b;    cout a >> b;    cout
