Problem: In this problem, you need to check if a given finite sequence appears as a sub-sequence in the Fibonacci sequence. A finite sequence is said to be a Fibonacci sub-sequence if it is contained in the Fibonacci sequence in the same relative order but not necessarily consecutively. 
For example, the finite sequence 2, 5, 8 is a Fibonacci sub-sequence.  But 2, 8, 5 is not. Write a C++ program to accept an integer M followed by a finite sequence of M numbers. Your task is to determine if this finite sequence is a Fibonacci sub-sequence. You should output the following:
●	true or false
○	true: if the given finite sequence is a Fibonacci sub-sequence. E.g. on inputs “3 3 8 13”  and “3 3 5 8”
○	false  otherwise
Input Format An integer M followed by M integers

Assumptions on Input
●	Assume that the integer M will be between 1 and 19, both inclusive 
●	Assume that the sub-sequence numbers will be between 0 and 5000, both inclusive

Problem: In this problem, you need to check if a given finite sequence appears as a sub-sequence in the Fibonacci sequence. A finite sequence is said to be a Fibonacci sub-sequence if it is contained in the Fibonacci sequence in the same relative order but not necessarily consecutively. 
For example, the finite sequence 2, 5, 8 is a Fibonacci sub-sequence.  But 2, 8, 5 is not. Write a C++ program to accept an integer M followed by a finite sequence of M numbers. Your task is to determine if this finite sequence is a Fibonacci sub-sequence. You should output the following:
●	true or false
○	true: if the given finite sequence is a Fibonacci sub-sequence. E.g. on inputs “3 3 8 13”  and “3 3 5 8”
○	false  otherwise
Input Format An integer M followed by M integers

Assumptions on Input
●	Assume that the integer M will be between 1 and 19, both inclusive 
●	Assume that the sub-sequence numbers will be between 0 and 5000, both inclusive

            flag = false;
            if(c == a){
                flag = true;
            }
            b = a+b;
            a = b-a;
            if(flag) break;
            if(a > 5000) break;
        }
        if(a > 5000) break;
