How can I eliminate one for loop in this code?

Hey @Pauline Wambui,

Try this sample code 

/ map to hold account name and corresponding account record
Map < String, Account > AccountMap = new Map < String, Account > ();
// loop through accounts and add name and account to above map
// TO-DO Simplify the account name ex: remove the whitespace and convert it to lower case etc..
for (account a: accs) {
    AccountMap.put(a.name, a);
}
for (Lead ld: leadList) {
    // if lead name contains in the account map
    // TO-DO Simplify the lead name
    if (AccountMap.get(ld.name) != NULL) {
        mapLds.put(ld.Id, ld);
        ld.hasBusinessAccount__c = true;
        ld.DateAddedToBusinessAccount__c = System.now();
        ld.InvitedtoBusinessAccountId__c = a.Id;
    }
}
