FUNCTIONS

Countvector <int>

numbers={2,1,3,1,17,2,1,3,5,6};

int target = 1;for (int i = 0; i < 10; i++)if(numbers[i] ==target)

count_ ++;

count(numbers.begin(),numbers.end(),1);

FUNCTIONS

Findvector <int>

numbers={2,1,3,1,17,2,1,3,5,6};

int target = 1, index = -1;for (int i = 0; i < 10; i++) if(numbers[i] == target)

{index = i; break; }

find(numbers.begin(),numbers.end(),1);

FUNCTIONS

Sortvector <int> numbers={2,-

1,3,10,17,2,5};

for (int i = 0; i < 7; i++) for (int j = i; j < 7; j++)

if (numbers[i] >numbers[j]) swap(numbers[i],numbers[j]);

Sort(numbers.begin(),numbers.end();

11321-SORT! SORT!! AND SORT!!!

11321-SORT! SORT!! AND SORT!!!Given N numbers. You will have to sort them in ascending order of their modulo 2 values, If there is a tie between even numbers sort them in descending order of their values, If there is a tie between odd numbers sort them in ascending order of their values.

11321-SORT! SORT!! AND SORT!!!

ascending order of their modulo 2

descending order of their values “even numbers”

ascending order of their modulo 2

FUNCTIONS

Reversevector <int>

numbers={2,1,3,1,17,2,1,3,5,6};

int size = number.size();for (int i = 0; i < size/2; i++)

swap(numbers[i],numbers[size-i-1])

reverse(numbers.begin(),numbers.end())
