+//  Count Palindrome Words In A String
+// Easy
+// 0/40
+// Average time to solve is 15m
+// Contributed by
+// Asked in companies
+// Problem statement
+// You are given a string S of words. Your task is to find the number of palindrome words in the given string S. A word is called palindrome, if it reads the same backwards as forwards.
+
+// Note:
+// Words are separated by one or more whitespace characters.
+// For Example:
+// For the given string “Madam oyo cat”, “Madam”, and “oyo” are the palindrome words 
+// Detailed explanation ( Input/output format, Notes, Images )
+// Constraints:
+// 1 <= T <= 10 
+// 0 <= |S| <= 10^5 
+
+// All the characters of the string S contain whitespace, lowercase, and uppercase English letters only.
+
+// Time limit: 1 second
+// Sample Input 1:
+// 1
+// Nitin and I are good friends
+// Sample Output 1:
+// 2
+// Explanation For Sample Input 1:
+// For the first test case, there are 2 palindrome words only i.e “Nitin” and “I”.
+// Sample Input 2:
+// 2
+// Madam taught us the level order traversal of a binary tree yesterday
+// We love coding ninjas
+// Sample output 2:
+// 3
+// 0

+//  Search In Infinite Sorted 0-1 Array
+// Easy
+// 40/40
+// Average time to solve is 10m
+// 33 upvotes
+// Asked in companies
+// Problem statement
+// You are given an infinite array consisting of only ones and zeroes, in sorted order. You have to find the index of the first occurrence of 1.
+
+// Example:
+// If the array is 0 0 0 0 1 1 1 1… then, the first occurrence of 1 will be at index 4 therefore the answer here is 4.
+// Note:
+// As the array size is infinite, the actual array won’t be given to you. Instead, you will be able to access the array elements by calling a method named ‘get’.
+
+// get(i) : returns the value present at index I.
+
+// Indexing is 0-based. 
+
+// Instead of representing an infinite array in the input, we give the index of the first occurrence of 1 in the input itself. However, this input will be completely hidden from the user.
+
+// It is guaranteed that the answer will fit in a 64-bit integer.
+// Detailed explanation ( Input/output format, Notes, Images )
+// Constraints:
+// 0 <= ARR[i] <= 1
+
+// Time limit: 1sec
+// Sample Input 1:
+// 10
+// Sample Output 1:
+// 10
+// Sample Input 2:
+// 1
+// Sample Output 2:
+// 1
