WebApr 10, 2024 · Initialize a variable count to store the count of occurrences of the candidate element, and set it to 1. Iterate through the array arr from index 1 to n-1: If count is 0, set the current element as the new candidate element and increment count to 1. If the current element is equal to the candidate element, increment count by 1. Web__builtin_popcount (x) is a function in C++ returns the number of 1-bits set in an int x. In fact, "popcount" stands for "population count," so this is a function to determine how "populated" an integer is. For example, say we have an int x with value equal to 12. 12 in binary is just 1100, and the rest of the digits are just 0's. WebDec 17, 2015 · You can use the division / and the modulo % operator to check the bits that are set in an integer. int main () { int a = 512, count = 0; while (a != 0) { if (a % 2 == 1) { … rolls royce assist
