Rotate function in stl

#1

How can we rotate anti-clockwise using rotate function

#2

Hello @Tiwary725,

To rotate right, we need to subtract the vector index. For example, you have to rotate vector right 3 times. The 3th last index of vector becomes first element. vec.begin()+vec.size()-3 will rotate vector 3 times right.
SYNTAX:
rotate(vec2.begin(), vec2.begin()+vec2.size()-rotR, vec2.end());

Hope, this would help.
Give a like if you are satisfied.
