The C++ STL contains the function std::count(), which is used to find the occurrence of the particular element in the given range. You can use this function with an array, string, vector, etc. To use this function, we have to use either <bits/stdc++> header or <algorithm> header....
As of MATLAB R2019a, you can use the “groupcounts” function to compute the number of times an element appears in a vector as a summary. In other words, the elements of the below output “GC” are the counts of the corresponding element values in “GR” (from the...
This means this function only gives the values of 1 or 0 because the container does not allow duplicate keys and returns 1 if an element with that key exits the container and zero otherwise. In other words, this container does not allow duplicate values, so the count() function always ...
