John is going through his family photo album. There is a total of N people
in the family labeled from 0 to N - 1.
Find out the number of members of his family who have more than or

Input Specification:
input1: N, denoting the total number of family members.
input2: X. denoting the minimum number of children a family member st
have in order to be included in John's final set:
input3: An array of N elements where the ith element denotes the parent
the in index. If the value of the element is -1. then that family member ha
parent
Answer:
0.21 & 0.78 respectively....
Explanation:
ch3oh=12+3+17=32 gm=1 mole ch3oh
60 gm ch3oh=1.8 mole
water (h20)=18gm=1 mole
120gm water=6.6 mole
mole fraction of ch3oh is
= 1.8/(1.8+6.6)=0.21
mole fraction of h2o is (1-0.21)=0.78
