Can you provide a code to queries to check if any pair exists in an array having values at most equal to the given pair and the other steps required given the following:
Queries to check if any pair exists in an array having values at most equal to the given pair | Function that performs binary search to find value less than or equal to first value of the pair.
Perform binary search.
Find the mid.
Update the high.
Else update low.
Return the low index.
Function to modify the second value of each pair.
start from index 1.
Function to evaluate each query.
Find value less than or equal to the first value of pair.
check if we got the required pair or not.
Function to find a pair whose values is less than the given pairs in query.
Find the size of the vector.
sort the vector based on the first value.
Function Call to modify the second value of each pair.
Traverse each queries.
Evaluate each query.
Print the result.
Driver Code.
